Hopefully I get a response, but I know you're a busy man. I've almost completed a piece with some tattoo work (simple tribal stuff), and did it on the tablet by hand in an overlay mode and whatnot, was wondering though if you had any other suggestions for digitally painting tattoos. Not a tutorial or anything, but anything that can point me in the right direction if there's anything beyond messing with overlay layers. Splendid work, reminds me of Caravaggio's style.
