Seems kinda flat imo. Also, tone down that light source, it's gigantic lol Work on your depth/lighting
Yea, he pretty much nailed it. Depth and lighting are the main things that need work. You almost fall into the floating head syndrome category, but not quite. Be careful of that in the future . Maybe move the text a bit closer to the focal, don't be afraid to do that. I do like the background, it's just so damn flat.
