I see a lot of demon/angel characters, but what I really want to see is the terrifying or elegant creatures of the dark and light. Got a demon that has the form or an animal? cool. An angel that looks like whatever the frolicking frick Galeem is? awesome. This also works the other way around. have a demon that looks like some abstract horror? or an angel that looks like some type of bird or fish, etc, that's also cool. If it doesn't just look like a human with wings/horns and a tail, then I'd love to see it.
