I'm not a big fan of most of the Harley Quinn designs going around so I decided to make my own. Here's my take on a more punk-styled Harely... think Harley Quinn meets Tank Girl (but with more clothes).
And here's my custom. I hand-sculpted the pants and jacket with some Aves Fixit Sculpt and gave the figure a complete repaint. I still have to add her signature diamond pattern to the right thigh and I also plan on adding some tattoos made from custom printed water-slide decals (although I've never used water-slide decals before, so I'm going to practice a bit before attempting to add them to this custom).
