Hey, I'd be glad to work something up!
As far as doing art for free, all I ask is that if he gets the image tattooed on him, that he sends me a picture. I still haven't had anyone get something I've designed them inked, so it'd be awesome to see someone get one of my pieces inked!
I've got several other tattoos I've been designing for people, so hopefully I can get all of those scanned in tonight, and if you don't mind, I'll just post the Reaper picture in this thread as soon as I get it finished.
