Like the pose a lot, the arm looks a bit weird probably need to increase the size of the left arm just a bit, more muscle definition would help a bit if he's suppose to be athletic, the colors really good on him though the background could've been much more interesting like for example could've used colors to compliment or contrast against the character make it more unsettling or give the feel of being in danger. Could've added more bruises and such and more of indication of what he's doing in the piece would be great. Still pretty good just needs some improvements.
