Avatar: 5/10 Jedi logo, tfuj! It shall burn like all those pathetic Jedi temples! Yes, I don't like the Jedi.
Signature: 7/10 Not bad. Easily accessible when I want to find a character. Classic.
Ava: 4/10 some weird... anime... trojan thing going on there...
sig: 4/10 colours make it clear, underline is cool. But it takes a little too long, for my liking, to isolate the characters in all that. I'm a sucker for convenience.
Avatar: Nice, and it's the Rebels, so kudos on that front, but it's a little simplistic for my tastes.
Signature: Clean, contrite, and efficient. Very nice overall. Nothing flashy. Good design.
