Initially, I thought you'd posted a low-rez preview image as the pixellation & graininess is very high. I was wrong. My thoughts:
1) This needs much better source images. Clearer, cleaner pics all around (this goes not only for the top & bottom backgrounds but also the progress bars and menu box.
2) Readability, with any theme, is key. You can't play what you can't see. While you've set the highlight to a solid color the rest of the text is pretty much unreadable, a busy background is the culprit here. Even dropping a darkening overlay on top of the bottom screen would help the text pop a little better. The same goes for the calendar and clock; those should've had designated areas designed for them instead of just dropping them onto the image wherever they fit.
It's great that you're trying to build AK2 themes, they're not the easiest to do. Just start with the highest-quality imagery before you get to editing and you'll be in much better shape as you go along. Let us see any updates you come up with.
