Yeah, it is a wide array of styles.
The artist I go to freestyled (edit: freehanded) my left arm to tie in my Megadeth tattoo with my Live Free or Die tattoo, neither of which he did to begin with. He will be the only one touching my skin from here on out.
That's why I haven't nailed down specifics, plus the artist will branch out and do things on his own when he actually sits down and is working in my skin. He is brutally honest if something won't work....I guess it helps that we were friends before he started working on me.
