I like it.
You should wait until some more of the framework is finished and then create this skin for the software.
Also, do take into consideration that there is much more to a theme than just the home screen, there are many pages, images and buttons that need to be created for a skin. But keep up the good work, develop the functionality of it, and it could be good.
The way the openMobile Original Skin, and my personal Green Theme is created, the way the software is actually designed is to have the four corners ALWAYS serve the same purpose: top left is volume, top right is home, bottom right is back, bottom left is media controls. this way, no matter what screen you are on, you hit that corner, and you will always get the same function. strong end-user functionality.
