Well the first thing I noticed is your lack of contrast. It only looks like you have about 3 or 4 colors. You could definately remove some of those, most of them infact. That's your main problem.
The only other problem would be the weird highlights on the eyes. They're kinda weird-looking in my opnion. Maybe tone them down, or just alter them a bit. That's just my opinion.
Other than that, it looks like a good piece. Monsoon definately has done his fair share of inspiring...
