Prety nice bro!

need more of a side shot to see your profile, I can't tell but I reckon the eyebrow furrow needs to be pushed back in a little, and may be slightly more
pronounced eye brows.

The mesh structure looks great & solid to animate on. your poly work is great!

The one thing I would recomend, and that I have to tell myself ova & ova again is:

over accentuate most things in 3D because computers tend to smooth off everything, modles, textures, animation.
