iOS7 Keyboard Design Concept - Revised

This revision takes the keyboard design one step closer to the aesthetics of the iOS7 phone keypad with its semi transparent background and fully transparent circular button borders, revealing the colours of the wallpaper behind it. The message area has a darkened and blurred version of the device wallpaper.

I've also used the new green colour, found in iOS7.1 Beta 3, as the accent colour, which I think ties in better with the app icon. For brand consistency, if the app icon is going to be green, I think the accent colour for the app should match.
