Ohh, you see, there's a biiiiiiig problem here: Art's awsome and stuff, if not for the fact that the girl's body is almost compleatly black, so you just cannot see the butt very well. Normally void and pure darkness characters do things like shading and lighting so you can see what's going on, or the void just swallows everything around them - you don't know how to do those things yet. That's fine, but it suuuuucks for this art specifically.
Ah well, you'll figure it out one day for sure! And in the meantime, the BG sky and character's creepy eyes look awsome!
