C&C per req:
1. Not bad; the lighting is a little flat for my taste; I think some fill camera left would have helped a bit and the crop on the RH side is just a little too tight; you' actually trimmed his hair a bit.
2. This would have really benefitted from a reflector low and left. When using brick walls, use the leading lines to bring the eye to the subject; in this composition, the eye follows the lines past the subject and out of the image at frame right.
3. The strongest of the set IMO, but I wish you hadn't cropped the hair frame right.
Just my $00.02 worth - your mileage may vary.
