I don't think it's worth salvaging. You have good separation between subject and background, but it looks like his head and left hand are floating in a sea of blown out highlights. The upper half (and left side) of the image is really, really hot and I think the light falls off too much below his right arm. (both lower corners). I also don't like the long, vertical crease and accompanying shadow in the shirt (his right torso). The light, being on camera axis, is pretty flat. I don't know if you had room, but I might have tried bouncing the light off of a wall or the ceiling. Overall, I think there's just too much contrast.
