Interesting. Very interesting. Its a rather odd piece, and kind of creeps me out, but at the same time I like that. Your colors and drawing style really make this a piece worth pondering on. I would have liked to see the lineart on the three heads on top tightened up a little bit. The scribbles in the mouth distract from the rest of the lines. I liked the pure black mouth on the main girl; its evident you took the time there.

Overall nice though. I would just caution the difference between sloppy scribbles and stylistic choice.
