Size matters
I think that having one eye a lot bigger than the other, when they dominate the picture like this matters a lot. Yes, cite Picasso at me all you like but in this piece, you're clearly not doing an abstract.
There are flames in the background and a guy who looks like he has a sword shoved through his left eye socket. A little gratuitous, but I'm trying to see the meaning in it, though there is a certain degree of failure here.
Backgrounds with a lot of empty white spaces are a pet peeve of mine - even a wall that is painted white is not the same as a filled white screen on a computer. I'd suggest doing something with the shading there - paint a few shadows on there, or even some soot, since the flames are that close.
The head of the guy himself (I'll assume it's male, if it's not, I'll apologise to your model) seems to be a little disproportionate, with the hair stuck to one side of the head. It kind of reminds me of some of the hairstyles employed by Mandy Morbid - long and colourful on one side, shaved completely on the other. Still, the look of the piece says to me that you need to work a little on the detail and then see where it stands from there. If you get a picture worth a thousand words out of it, I think you'll be doing well, because I can't see it at the moment.
