One thought, why not use a different image on your background, I'm all for duplicating good designs (mine was obviously inspired from Motofishes) but if your gonna go to the effort of creating your own cab/controller at least personalise it and make slightly unique artwork.
When looking for a backgound image to use on mine I short-listed literally tens of images and that was with a very limited critirea (space, black, blue, silver). Spend an evening or two going though DeviantArt, there or thousands of great works on there, just seems a shame not to make use of it.
