The former eyes looked fine to me, better than the new actually, they are... too opaque, as if he's gotten blind. If you're concerned about mirroring, you can always create two planes for the pupils and put them in front of the eyes, as many blizzard models do (check Jaina's portrait for instance).
Don't worry about the expression too much, it is fairly easy to change it by creating a bone to animate the mouth's corners.
As for the body though, I must say the abs looks strange, firstly they are too large (or the chest's upper half is too thin, you decide) and secondly they are very marked at the centre, only to fade completely toward the pelvis and pectorals, as if he had no muscles there. Though I'm not sure if it's something about the UV map or just the texture.
Still, pretty nice job overall. Can you post the wireframe please?
