hmmms, (goes back and looks at last pic posted) Ok, I think I may have figured something out.
On your shading, you may need even darker shads to the outside of the body. Also, have an idea where your light source is coming from so that, for instance, if the light is coming from the right of the character, the left side of the body, arms, legs etc., are all going to be even darker than the shaded areas. Does that make sense?
