First of all great pic! Second the best part about this one that sets it apart is the hair! I don't know if you were just finishing spinning around or if there is a fan off to the side but its a really cool effect, lol maybe its just windy!
As all your pics you look really cute and your smile is very nice as well. Its a very clean picture too, you have allot of white on and that's so tough to keep clean but it helps to make it look fantasy-like i think.
