Really liking the diffuse! I would suggest that you try editing the curves just a bit. I think it would be nice if there was perhaps some painted in top down lighting, or rather a little gradient to where the upper half is lighter than the lower half; just a suggestion though. :)
Yeah the pose is a bit camp :3 It's a really nice piece of work though :) My main crit is the brightness of the legpads/kneeguards, it's similar to the rest of the model and it's fighting for my eyes. I'd darken the legs, change the stance and maybe add some more blue/cyan to the diffuse more like the D3 model seems to…
