Hmm first full body skin (very very first "skin" was shirtless Olaf). Although mainly it was just recolouring, I added glowing scratch marks, weird designs and tattoos, and some armour rust just for kicks.
So hopefully he's creepy enough now, cause '[i]t's only fun when they run.'
Edit: Now added a Warwick with darker blue-grey fur, named DarkerTaint. Does not appear in preview
