Well I agree that the pad layout is pretty darn good. If you use the same colours on the mapping controls then you can very quicky associate them to their real life equivalent. The only comment I can make though is that there's too much "blue" (the dpad, R and X buttons). Maybe the dpad could be closer to the purple end of the spectum. Also if the select button was more a pastel orange, it would tie in closer to the start button.
