I wouldn't put mine in costumes, as I can never come up with, or draw, costumes. Plus, my characters are odd enough looking. But I'd certainly draw them in some frightening or strange pose. Everyone else can draw theirs in costumes, or however they want. It doesn't matter!
I suppose that would work. I'm so happy with all the ideas yall are coming up with. In other clubs I have, hardly anyone participates half the time T.T But you guys have some great ideas! Hopefully we get to do a few, at least.
