If I'm modeling your game mesh. 
I'll need reference images front ,back ,left side ,right side ,top ,bottom.
And at lest 3 prespective images.
All in exact full color.

Not saying anythings wrong with your mesh.
but if your going for realism.
Might be helpful if you used human reference images using the same human for each view.
