I was quite intrigued by your earlier walkers but I didn't find them as "finalized" as they could be. Colorschemes and walking mechanism were both nice in both cases but they didn't add enough "Wow!" to the creations to make them really standout. Thankfully, same can't be said with this DvOurr: It's full of charachter and style!
The mixture between mechanical and biological, machine and beast, clean and chaotic works very nicely. This creation reminds me somehow of the Oliphants from the Lord Of the Rings: Large hulking beast which have raised to serve as walking artillery platform. I really wanna see more of these creatures in their natural habitat: in middle of battle!
Very good work!
