Tips on making my icon better?

[Chief-Oblivion]

Well it's not complete but I want this one to look better than my last one. Any tips on how I could make this look more realistic? Again, it's not done but it's easiest to add details before you finish it.

Not sure if you can see his mouth, a current fix but he does have a small smirk.

It's meant to be a drow (dark elf)

The hair needs shading and erm, lines on it so it won't look plastic, you know...
I can't see the mouth :/. The face is pretty good though

Well it's not complete

That will be added in time, I am looking for suggestions as to what to add that my other icon didn't have.

my latest, pretty much done unless I get suggestions.

The mouth and eyes need work.

Yeah, the mouth was meant to look like a smirk but it turned out looking like some crappy smile. Working on that fix, I think I am just going to fix this up until it's worthy of blizzard... It will take ages though. I am going to remap alot of it, I'll post the results here when I get it to a presentable stage.
