It's a good image and it works well. I kind of like the fact that you actually don't have any black in it at all, but made it brighter, possibly to fit the signature banner better (something I never really dare to do).
I'm also fond of the space you've left around the icon, I mean anyone with PhotoShop can add a shadow, but you've centred the image, and the space makes the whole thing feel more comfortable in a way.
9/10 because there's no Edward in it.
