I'm not into gangsters, but nevertheless this pic is still good.
I love skinny guys (I'm a girl, fyi), and this gentleman has what I like. The abs are a little too blocky though, maybe a smaller, and/or lighter brush? But the ribs and the rest of the abdomen were done very well.
And I like the tats. Did you come up with these or did you base these off of pre-existing designs? I especially like the eagle. From what I can tell, it's original.
