Wait I am confused here... why do they make black balloons?
40th and 50th birthday parties.
My only comment that hasn't been said is her arms - her arms TOTALLY kill the hanging effect for me. Far less "hanged to death" and more "pretending to hang to death." I understand it wouldn't be easy to do that in heels on a milk crate, but that's my $.02.
If DOF was more slim, it could be a more attractive picture, but I like your editing style. Also, the watermark, I get where you're coming from for the web sharing basis, but when I opened up this page I saw balloons, then a pretend graffitti watermark. It turns a lot of people off and kind of sets the mood for the photo early if you're not careful. I'd make it more simple, and give it more opacity.
Whether that counts for anything or not is up to you. Great idea, though. Good model
