Here are the comments that I came up with, as I was doing my share of the judging for this contest. I copied a URL for the image posted with each entry, and hopefully they all still work here.
Solar Explorers - $5 category.
This is a cute rover. I appreciate the unorthodox construction, using a set of technic beams to do a stud reversal. I'd like to see a little bit more color, though, as this could make a bigger visual impact.
Nathan's Rocket - $20 category?
I'm guessing that this is intended for the $20 category, although it's a bit over in parts count. I very much like the two different radii of the struts for the fins, it's great look. I don't really like the light gray bits mixed in (especially the 3-way pieces, which stand out alone). I like the checker patter on the virtual color scheme, but not the blue? of the engine pods.
Vic Viper - $5 category.
I like the front prongs/fins and their attachment looks good. I'm curious how strong that is, whether they wobble or move up and down. I also like the yellow and dark bley together, although the placement is a little disorganized.
Unnamed starfighter - $20 category.
I'm putting this in the $20 category, as it's well over the part count for a $10 set. The engine or bomb on the bottom looks really cool. I like the various prong shapes, and the small angle between the front and back wings. It looks very rectangular in the orthogonal views, but looks much better in the 3/4.
Lunar Mascon Explorer - $50 category.
There is a LOT going on here. I appreciate the attention to a back story, and the wide variety of play features. It's cool that the pod and rover things connect together, although some of the connections look a little flimsy. Overall, I think I'd like to see one or two fewer vehicles, with a little more detail and solidity worked onto those remaining.
Vendetta Fightercraft - $50 category.
I like this shape of this thing, nice style. I also like the color choices, but I wish that there was more lime.
M83 Diamondback - $50 Catergory.
I like the dark green, and I'm a big fan of the shape at the nose. I also like the fins on the edges of the wings, and the engines there. Nice job greebling the underside as well. I fear for the strength of the wings. I think that I'd have preferred to see this trimmed down to make the $20 category. It's far too small for a $50 set, it just doesn't seem worth that price on the shelf.
SFS2 Shuttle - $20 Category
Decent work on the greebs, and the cockpit arrangement isn't bad. It just doesn't feel like a cohesive whole to me, though.
Blasterbike Burnout - $5 Category
I think that the orange bike is great. The green and black one, less so. It should probably drop one of the greens.

Pinchbot stuff across various categories
I like the idea of scaling the pinchbot shape to different sizes, to make larger bots and stuff. I would prefer more details or color, though. The large expanses of black on the big craft just aren't exciting.
CYGNUS Corp. EPERON - $20 Category
Probably should have added something to the set to use more of the $20 part limit. It's a cool shape, although the colors are just a tiny bit spotty. I see that it was entered a second time with a base. Much better playability.
Limeroof Loft - $50 Category
Where's the lime roof? Seriously, though, this appears to bring a lot of playability to this price point. The colors are also well organized, and it generally looks good. I'm a little worried about the narrow base, as it might tip over a lot during play.
Lunaropolis - Various categories
These are all pretty well designed, but I don't understand why you chose to ignore the price points set in the contest rules, to use your own. Lovely stuff, though.

Yellow racing speeder - $5 category
This is pretty stylish. Personally, I'd probably go with either the blue or black, but it still looks pretty nice.
Galaxtic Miners - $10 Category
Fun playability. Seems to basically be Power Miners in space, though.
Pilot Grizz - $5 Category
I really appreciate the inclusion of serveral alternate models. Good color organization. It's a little boring, though.
Parasite - $20 category.
This is pretty awesome. Tons of play features, and it looks great!
Police Mecha - $20 Category
Well done. It looks quite good, and appears to be very posable. It could use a nice sticker treatment, with some Police logos and so forth.
PDGON-37 Manta Ray - $20 Category
Sorry, the rules aren't to determine a value, they're to build to one of the price points offered. It looks pretty good, though. I like the wing shape. I wish the canopy was a different color, I don't like the trans orange with yellow.
Lunar Sports Cycle - $10 category
This seems small for a $10 set. It has a fun shape, though.
Interplanetary Racing Circuit - Various categories
Some of these have a bit of a rainbow warrior feel, while others are quite nice. I like the tan and dk bley one (unsurprisingly).
Stefan's Space Creations - various categories
I appreciate the inclusion of two different ships in the larger set. Both ships have too much black, though, it doesn't photograph well, and doesn't pop. Plus, they look so similar, it's hard to tell if they're on the same side, or enemies.
Fatayanke - Various categories
Great job fitting an entire fig into a suit so small. It's quite cute! In general, these seem to have good playability. The large ship looks like fun, although it's a little jagged for my taste. Nice idea with the detachable escape vehicle.
Scout Bike - $5 Category
Good color organization. I think that the wheels should be larger, so it can go off road.
Jungle Stalker vs. Cyclops Assassin - $20 Category
Well done! This is quite nice!
Light Cargo Transport - $20 Category
Great play features! I like the landing gear, and the large cargo area. I wish that the engines were a matching color.
Neo Classic Space Lunar Lander - $20 Category
I seem to recall a rule about not rehashing old themes... This is pretty nice. It looks good and like it has a lot of playability.
My comments for the larger set are similar. Great play features, and nice remake of a classic, but certainly seems to break that rule about old themes.
BLACKSPACE LC-1V RECON MECH - $20 Category
Crazy arms on this thing! It looks good, although I'd like a bit of an accent color, I think you've used almost enough trans lt green for it to do the job.
The Infiltrator - $5 Category
This is a neat little ship. It crams a lot of parts into a pretty small shape, though.
Anvil-class starfighter - $20 Category
Cool ship! Interesting shape, good color blocking.
Zombie Scene - $10 Category
I'll take zombies as sci-fi, no problem there. I like the use of lighting in this creation. There seem to be a lot of parts used for the grass, that would probably be better used for more play features.
ChromaTeam vs. Vexx - $20 Category
The chroma team idea is cool, and I appreciate the throw-back idea. It seems like you tried to do too much within the parts limit, though. It seems stretched thin.
The Paleman's Stuff - Various Categories
These are all well built, they look good, and playable. The only one I"m not really feeling is Squingy McGee, it kinda seems too much like a pod-racer.
CH-90 Heavy Lift VTOL and Mobile Science Lab on Charia - $100 Category
Wow, long name! There is a LOT going on in this set. It looks like there are some fun play features, but the ship is quite splotchy in color scheme. It's very cool that it picks up the building, though.
Biotron MOCs - Various Categories
Some of these are quite nice. They all at least have nice features, and clean simple color schemes.
SF-1 'Starskipper' - $20 Category
This is a neat little ship! It seems small, though, even if it's considered in the $10 category.
Mechlomania - $20
Great play features! The gun arms look bad to me, but the rest ain't bad, and they're playable.
Malkiir defence fighter - $10 Category
Interesting color scheme. I can dig that, but it's just so flat!
Barrel Bot - $5 Category
Barrel Bot is awesome! It's cute, and I especially like the wrench antenna on the back. Why are its feet blue?
