I looked at my custom Two-Face figure which I did a while back. The main change was a repaint, but I remember someone saying that I should have sanded the hair down. Now that I own some grinding stone attachment heads, I did just that. I also painted the hair on the scarred side white (but still brown at the roots) to have more of that dichotomy going. There's also a bit of a black wash on the scarred side to have a little of that "burnt" effect. To increase the effect, the hair on the handsome side is repainted black (from brown). The comparison photo shows (from left to right) the original figure, my first repaint, and the latest version.
