I would leave more space at left and have his hand uncropped. Others than that I feel the post like, "You want one more?" kinda thing. Is he point to cam? I think he point to the cam right? but somehow looks like he's showing 'one' wif his finger.
what do you want us to look at? there's no place of dominant interest or focus (i don't mean blur-sharp kind of focus). you want us to look at the hand sign and guess what he's trying to say...or look at his face and read his mind .. or both compliment each other to get the message across?
either ways, the message is neither-here-nor-there. to me , its just a person pointing his finger upwards.
nitpick about the lighting...there is no separation between the arm, sleeves and body.
somehow, i get the feeling this shot is intended to be an 'attitude' picture? but the elements of 'attitude' are somewhat not there... the angle, talent's expression, lighting.
