Great connection with the camera and you have captured an arresting expression.The lighting is okay, not too dramatic which is suitable as the facial expression enough, you don't want to rival that with dramatic lighting. As a general rule put the eyes above the half way mark though you don't need to do so here. I like the crop into the top of the head and chin. Try this image as a square crop and see if you like that more. Though perhaps the dark areas around his head work well just as they are.

This shot is making a statement about emotional distress. Black and white is dramatic so a good choice here. The face is centred in landscape orientation, while many portrait photographers would have used portrait orientation and had the man's face off centre. It is not wrong to do it your way but often such choices are less dynamic. Try the other way and see if you like it more. Another suggestion for portraits is that when shooting hands, try to have the edge of the hand towards the camera, minimizing the backs or fronts of the hands. It is usually a better look. Very sharp and an unusual subject which catches the viewer's attention.
