The chest looks still a little to plane / flat i think dunno...
an shot of the model with the skin (well at least would you got till now) would be good ...
The model is too detailed, which is wasted in game. This unnecessary detail also creates an unnecessary file size. Other than that, the staff looks a bit odd. I'd attribute it to the color scheme. The orange doesn't go with the shoulders or staff. I could see this being used as a larger sized unit if it weren't for those things.
