Its all well modeled of course , just that mainly the torso is a lot more complicated than the legs and the head. Even though im using Maya id like to know how you do your ambient occlusion by the way .
Well, there are many ways of processing, but when I personally use it, I just add AO in material, on the color shaders layers (color "slot"). This way you can add AO on precise parts nor all the image. Also allows to tweak the precision per shader, which is so much faster when rendering Hope it helps ?
