Okay, painting's almost done. I've taken a much more gritty, realistically shaded approach to the style. Lots of contrasting colours, too. There's still some cleaning up to do as it was a comparatively messy process to what I'm usually used to.

Oh yeah, I think the painting on the metallic parts is going to be completely redone, I really screwed up with the reflections there. Just posting what I've got so far to see if this sort of style tickles yer fancy. ;)
One more thing: I'm not entirely sure what the process is from digital artwork to the actual application of the tattoo, but will the one you get be an exact duplicate of the design you choose? I'm curious because I've been rather obsessive with the previous versions of the design, in terms of keeping it as neat and clean as I possibly can, right down to the pixel. :P
