I like it.
Your background looks slightly blue. Navy blue instead of black, but perhaps the background is blue. He has pretty good skin tones but if I reset the background, he turns green!
Perhaps just a little, or a little more, back light to separate him from the background might be an improvement.
Adjusting Vibrance and Saturation sliders a bit right would give him a bit more colour, warm his skin up a little and make him a little less pale.
All very minor stuff. It’s a good photo.
