These girls look pretty sinister! Very nice work with the full hair on each of the characters. I like the fire detail you have at the bottom, almost like this is hell and these three characters are going to be your "hosts" for all of eternity. The fact that the one in the center (Boosette?) is just ready to grab the viewer is neat, making the viewer feel more involved in the piece. Chompette looks like she wants her snack before the middle character gets to the viewer.
Nice work overall.
