Not a bad turnout. They were all awesome, but I voted for Aiora's. I like the character lust (there's just not enough of her art out there ) but the sigs just have her, the words and a design. The Envy sig got the green color (green with envy) I don't know if that is done on purpose by Aiora though, and the greed ones have the dollar sign and the gold coins.
And the gluttony one by homunculous was quite humorous, it was hard not to vote for that one.
