sleeve design for a friend.

not matter how much in the past that I have insisted that I am no good at this sort of thing. My freind insists that I design his tattoos. I am flattered honestly, but it scares me that my designs are on his skin... lol also he had an actual tatto artist tell him that something I designed and he had put on him was crap... everyone is a critic I guess but still... I'm destroying this guys skin QQ please dont reuse this ever not that i expect that anyone should but xD; i thought I should ask.
