What their website says about copyright:
So basically they don't own it but neither do I. I'm not sure if that makes it really "creative commons" or not. But anyway, without further ado, here's the sprite I made!We do not make any copyright claims to the comics you create using ComiPo!. However, you may not claim any copyright to any visual representation such as characters included in ComiPo!.
She has six expressions, and I can easily edit them or add more if anyone's interested. I'll probably make more sprites later too - ComiPo makes it super easy.
