It's finished! I had some inspiration from Equestria Girls a little when I was designing an outfit for the fire warlord. The ice guardian is just wearing a nightgown because she is a kid. All three have their own individual goals. Pandora stands for innocence since she represents the innocence Uniqua lost as well as her fear. The other represents her rage. I don't know if I'll ever be able to add the other images to this. They won't load right now so, I can only show you this one. If you wanna see how I incorporated Uniqua's soul into their designs, just zoom in. I can't get those shots to load here, sorry.
(Let's pretend I didn't forget how to draw bat/dragon/demon wings-)
