About Chuck Norris: it's quite nice, but lacks some life, it's... you know, boring. Maybe that's because of those unlively colors.
signature with b00bs: not bad, but in my opinion white is too white. Wonder how it looked if it was some different color, so it would be more visible. @edit also maybe some cool stuff on both sides of signature, liek, some small, not attention-drawing but filling c4d etc.
Last one: this time it lacks some action, right is packed and such, it's nice, and left is too silent, nothing out there. Also noise (whatever the effect is called, I'll call it noise, you know, on hands etc.) is a bit too strong. Aaaaaaaaaaaand could you show me the stock image? Because it kinda has a feel like not much was done to it D: [maybe I'm wrong].
