ok just checked your site out.. you're a real pro and the amount of jealousy im experiencing right now is dumb high, you get to shoot all those guys? Lupe is my favorite MC out right now (and J.Cole)
I'm not a fan of the very dark vignette in 1, 4, and 5. I'm also do not like the centered subject in 3 & 4 either.
These were all shot on very small f/stops. Have you considered shooting with a larger aperture to render a more pleasing background rather than residential housing behind a fence?
lol if you're a beginner....I quit. You have photographed alot of big names. My daughter would faint if she even thought I talked to someone who has photographed Justin Bieber. Nice work newbie. haha
