I've been seeing a lot of fan pieces of these three recently. I thought I'd take a crack at it (GET IT!? CAUSE AMETHYST HAS A WHIP!). Pearl's my personal favorite, but I can see how Amethyst is the most popular; mainly because she's much more fun to draw. I was gonna add Steven himself, but he deserves his own piece.
