Not bad, put a little more care into managing your whites though. #3 (In future please number your images, it makes responding much easier) would be a really great capture if the exposure on the whites had been tweaked just a little more.
I thought "Not bad" too, unfortunatley. I don't wish to sound harsh, but I can't help thinking that we should be bowing down in awe and admiration for a guy who has world renowned, multi-millionaire rapper
P Diddy in his portfolio.
There are some odd compositional choices there OP, and some pretty aggressive post-production.
-In the first image, I reckon a little more time could have been spent getting a good looking swirl of smoke and the cropped top of the hat is a little distracting.
-The second I quite like apart from the blacked out shoes. He looks like a recent amputation patient.
-The third would be GREAT without that big black label on his arm.
-Fourth is great, great, great.
-The fifth. Mr Diddy is too far to the left and he has a weird thing going on with the background right by his head.
-Sixth - great.
-Seventh - Something's not right here. The overall atmosphere of the shot doesn't really match the pose and the smoke. It's a bit too bright and "nice". Plus, the white's are a bit green.
-Eighth - like it, but for the cropped fingers. Other than that - great.
-Ninth - Bizarre background choice. His head and arms are almost perfectly camouflaged against the busy and surprisingly similarly coloured background. And there's a traffic cone where there shouldn't be one.
A couple of great one's in there, but with the best will in the world (I'm sure you're doing perfectly well) and with all due respect, I would expect a bit more from someone who makes their living photographing some of the richest, most powerful people in the music industry.
