Not bad, but your key light is too far above his head. Feels as if you're lighting the top of his head more than his face. Big indication are the catch lights that are non-existent due to the light's position. Hope this makes sense! Keep creating

Pretty good overall. As Derek already mentioned - key is too high and you are lacking catchlights. Lack of catchlights here gives a kinda creepy vibe IMO.

I think this is an instance of where having high broad lighting is not really working. If your strobe has a modelling light use it too see where the shadows fall. The way in which his far away eye has a half glint gives the image an odd really creepy look. I think one thing photographers all have to remember is, as humans one of our hardwired skills is reading facial expressions.......what does his facial expression say to you? For me the expression generates fairly negative vibes, not an image I would use. What did the client think?
