3D Robotic Dog Critique

Ren

Hi all, this piece is heavily based on the not yet released title "ReCore" (XBox One game). Considering there is only a Cinematic trailer and a few images online to go off of, I did my best to replicate it, making my own changes and solutions for places that were out of view.

I'm looking for any way I can improve my textures to create a more accurate depiction. Although I'm not going for a perfect 1 to 1 obviously. 

Thanks all!
