Mac's right, there's not a lot of room for creativity in layout style for screens this size. The most important thing is to make sure the screen real estate that is there is usable. What you have there looks about right.

The 3x is 2.8" and the T2-c is 2.4" so the size is pretty much as near as makes no difference when working at this size. If you're creating buttons for both, make them big enough for the smaller screen and then they'll be fine for the larger one.

For optimum clarity of the graphics make sure you're not stretching or squashing any of the buttons in VTPro as it doesn't handle this well.

Also, always take into account what hard buttons are available to you as duplicating them on screen will just take up useful space.
