It seems you've been sucked into the ZBrush addiction. I expect to see you in some sleazy backroom laying on a cot with you Wacom tablet and blurry bloodshot eyes feebly pushing polys aimlessly around.
Looking on both of your human characters what is needed is some sparkle in their eyes, and in the case of your female model a little moisture on the lips. I don't know if you've told us, but what are you rendering in? Probably the fastest way to achieving a little sparkle in the eyes would be post in a paint package and some fake SSS in the ears. If your rendering in a 3D package you can define the regions and then add specularity and perhaps a little SSS. The models are really Great, so I would take the extra time to push them a wee bit further then I think they would be Top Row candidates! You've got my vote .
