Tattoo design - from text to doodle to digital

A friend of mine on twitter had mentioned wanting a tattoo, and had something in mind but couldn't quite get what was in her head into the world, so I offered to design a little something-something for her.

So I quick whipped off a design on some paper with my very limited palette of Copic markers. This was done on a sticky-note style pad of paper. Same general size and all that, it just wasn't sticky, so a non-sticky sticky-note, right?

Not exactly what my friend was looking for, but she liked it - said it was a spin on the design she hadn't considered before. I'll take that as a compliment. Below is the digital version.

If you're unfamiliar with the character, it's a representation of Richard the Undead Warlock from the webcomic Looking For Group [LFG for short] by Ryan Sohmer & Lar deSouza of   Blind Ferret Entertainment.
