I received the very first completed CS in the game. I need 4 more before we get this show on the road. :) I've been drawing doodles of my character so expect to see those lol.

I am going to say this. The more detail your CS has (not over-detailed or "fluff" just a sufficient amount), the better chance you'll have. I do not accept skeletons. CSes need MEAT!

Also, I was going to add "Aura Color" as a CS option, but as Sudkurve has done, it's easier to just mention it in your character's written appearance if it's applicable.
