I just love the look of this. So smooth, simple colours, strong shading, and good gesture. I'm torn as to whether he's charming and confident or kind of a cocky ass. I can't decide! That's why I like it so much though. He's in plain sight and yet so mysterious. I want to read a story about this guy.
The position of the hands really pulled of the look you were going for. Good with the shading around the eyes, and you have a way with the color. i would fail miserably if attemting a bluegrey picture.... *i think i will be faving alot of your work*
