I think yours here is better. jmspencer's pic of you above looks, well, TOO realistic; it doesn't look like Gilly-in-costume, it looks like Gilly-in-serious-drag (if any drag involving that sort of mustache could ever be considered serious :-) -- Which is also fine, of course, but it depends on what effect you're going for in a userpic! But it would be a shame not to feature the sombrero.

Eet ees Love, señor...
