A Pink Bunny for Valentines -doodle (Patreon)

Yes, the demon gurls are everywhere now in my art pages and with some bunnies friends. Even if the first concept for them was really just a simple character design to practice ( force me ) to use just one color per drawing, today they are a big part of the oc drawings in my notebook.

This one is just a doodle for a concept art of them. what you think about them? Should we invoke a third demon sister?
