Snape bust rough up, need advice

[PerroNegro]

Hello, i need some tips on how to sculpt a bust of Alan Rickman as Prof. Snape, here is the first rough up i did, i'll work on the details later (just got back from work and i'm tired) i specially need help on the eyes, since i can't seem to get those right, here are the snapshots:

comments and critiques are welcome, cheers.

Ok, i had some time to work on the features, refined the shape of the face a little, add some bags under the eyes, still needs some work on the eyebrows but i guess it will be ready by the weekend.

Actually it looks really nice, especially head on. From the profile not quite there.
Good job.
