I just tested your wallpaper on the phone an hope you don't mind me tinkering around in your sketch.
If yes, then I promise I won't do it again. I made some adjustments in the barwork (softkey a tad higher, status a bit lower) to make sure it's not too close to the text and that's easier to explain via an image. When working with Theme Studio 2.2, keep in mind that it shows the look of your theme on the older 3d Edition handsets. In the newer 5th edition ones, diabolical, the middle softkey text is bigger and located a few pixels higher.
If you plan to divide the softkey area into three parts via drawing vertical lines you drive best with a width of at most 76 px for left and right softkey and 80 px for the middle one, with a space of 4 px between them. This way, your softkeys will work fine in all languages, including Nederlands, Türkçe and Español.
