Daily UI #005, App Icon

Hi dribbblers !

Daily UI day 005 - short thriller with dramatic moments.. in other words, designing an icon.

Icons designed for Noisli App (http://www.noisli.com/) that lets you listen (in the same time!) wide range of sounds, starting from raining via fire and thunderstorm and ending up on coffee shop.
It's my first app icon, so designed two version and not sure which is better. A or B? Any ideas what should be changed? Hope for good advices from you.

Pssst DRIBBBLERS, if you have trouble with concentration, http://www.noisli.com could be helpful :)
