As a small crit, The use of strong black in the diffuse is a sometimes a little strong on your models. In the top model this is very prominent in the scarf and the bottom of the jeans. You also have seams on the models, I have noticed this on a few of your latest model screen shots, the seam is down the middle where you have mirrored the mesh, so it needs a touch up with a 3d paint app to remove them, though I am also wondering if you have done something odd, like not weld or mirror both side of the mesh, and its made of two 'separate' models, that are not joined in the middle, my instinct is telling me you may of done that, but without downloading the mesh I cannot know for sure.
