I like your use of color and the overall simplicity of the design. However, I would make the buttons at the bottom a little bigger for a touchscreen phone. Also, the "100%" circle (I assume it's supposed to display battery life) in the first image is off-center, I don't know if this is on porpose but it looks a bit off to me.
Thank you very much! Oh yes that circle (make-your-clock widget) was a pain, I tried hard to get it right but gave up and settled on this position, and yes it is displaying the battery. And the few days I had this setup on my phone (a samsung galaxy S2) the icons worked just fine, but then I do have small-ish hands. These screens are just captures of my phone, nothing was done in Photoshop or outside, even the dock icons were made on the phone itself using Simple Text widget.
