Thanks man! Glad you like it.
As for using the design, what I've been telling people is that YES, you can use the design if you'd like. What I ask in return is simple enough -- I'd like a photo of the finished tattoo and a monetary 'donation' of some sort ($20, for example, or whatever you can afford/think the piece is worth). This is really just because I'm actually trying to make a living off of this whole 'art' thing, so I need to stop just giving everything away, heh.
