iOS7 Keyboard Concept Mockup

With iOS7.1 Beta 3 it appears that circles are the new black. This got me thinking about how the iOS7 keyboard could be designed to look more at home in a circular world. My curiosity led to this. You may notice that I moved the "Speech to Text" button which is always being inadvertently activated. In doing so, I also moved the "Send" button. Thoughts?
