Looking pretty good so far - I like the whole wolf-like Dr.Doom theme you have going on.
The modelling seems okay to me - the only possible thing that I may change is to give the hood a bit of depth as it looks extremely thin right now. As for textures, I applaud the rust look but for me, it looks a bit random - take a look at this image created by Leigh Van Der Byl as a sort of template
