Lots of great designs here, but I'm still finding myself partial to the Mimi/Urlea submission. It's the one I could actually see myself wearing. There are many other that I like and/or think are "good designs", but wouldn't necessarily wear... I would change the sleeve color though (make it darker and maybe cooler).
Tied for 2nd, for me, are Urlea's Daisy design and the Eden/Crazy Canuck "around the world" collaboration (although I would seriously tone down and maybe somehow abstract the place markers).
