Mine too! I have a list of ideas written on the back page of my sketchbook and "skull with heart eyes" was at the top of the list (and the only thing I have actually been able to cross off the list so far).

I think the scribble monster has potential as well (not the actual monster I've drawn so far, but the *idea* of a scribble monster, so I'm going to try to attempt a few more of those).
