This is Giosha's (Sirtiefling's "daughter" - hey, I created her and we're both tieflings) Pathfinder look. In Eberron she is, well, very "4e", but in more traditional settings she's an eccentric one. Tiefling's are supposed to be eccentric fantasy mutants. Eccentric is GOOD.

PPS. If there's someone who knows these characters o mine, then you'll probably notice the gothy attitude here. That's usually Angel the elf's fashion, the Eberron-Giosha is into leather-biker-anarchy look. I should probably do Pathfinder-Angel too in the future. Her design is pretty interesting...
UPDATE! I hate fixing and modding "a finished" painting, but there were several things that had to be corrected.
