Definitely agree on camera angle and lighting. The guy's pose is a bit wooden as well. The right arm on the couch is awkward. If he's leaning on that arm, push the right shoulder up and arch the back so it shows the weight being placed on his right arm. I'd also tweak the left arm. It looks like a mid-action shot - not at the start or end of the motion but somewhere in the middle, so it looks less dramatic. Also, whatever light is causing the shadow on the couch, kill it's shadow properties. It's muting the couch's color and further blurring the guy behind it. Hope this helps!
