Love the design of this, the charecter has a familiar yet unique estetic that sort of mixes Diablo with Pokemon in a way. Really cool. I also love the color palette, especially the reds and the coloring of the claws. They almost look like ruby's, which might be intentional but also really cool. I also like that the armor, together with the red bits make it difficult to tell if the charecter is a demon or robot or both or none of the above and just armor? The face is also really cool and has a strong feel to it and for some reason it feels like the charecter is blind? I draw this conclusion from the mask over his face and that he looks subterrestial? Might be my association with Diablo? ;)
If I were to give some critique I'd like to have seen a bit more contrast between the right side of his helmet and the metal piece on his chinn as they now meld together a bit too much making them hard to differentiate on the normal-resolution piece. On the highres it's easier but a bit more could have been done, perhaps some rimlighting or stronger shadow. Next, the anatomy is great but if I nitpick a little I think the angle of the claws on the right foot could be finetuned just a smidge. (Motivation for 4.5/5)
Otherwise a really cool charecter, also enjoyed the tiny backstory in the description :) Well done.
