Hey!
This one barely qualifies as a custom. I received the Long Halloween boxed set (Batman, Joker, and graphic novel) from a friend last year, and while I loved the figures enough to pick up many of the others, I never liked the paint job on Joker's head. To fix it, I based the head in black, and dry-brushed the rest. Simple as that.
I know it's not that spectacular, but the figure itself looks one-hundred times better.
Tell me what you think!
