The Odom needs more work. There's still some shine on th cheeks around the nose... get rid of it.
Van Exel looks pretty good but as Kevin said, lower the saturation. And bump up the brightness a bit... he looks kinda dark in that pic.
Marbury... again, the skintone is too bright... lower the concentration. Fix the mapping around the mouth. From that pic, it looks like you used Tony's headshape as a base. My advice is, do the bhed first, then the mapping and then tweak the headshape using EA's as a base.
Good job all in all
