I'm really bad at naming things, but I would color at least one of the smaller examples, myself.
If I color it I'd probably do it on the computer, but I need a mouse to do that. x__x I guess I can tomorrow
Sorry, don't mean to make more work for you. ^^; Since the version on the side is so detailed, you might be okay to leave it as is. It's nice to see the clear outline of the dress, too, since sometimes when people color, the small versions can get hard to understand.
I like the green variation, btw. But that's probably because I like green. ;p
