Looks great! There's a tremendous amount of satisfaction in personalizing one's instruments.
I've got a black Steinberger, and I removed the cheap metal knobs and replaced them with knurled black chrome with large abalone inlays. Just a little effort, and it's styling.
A little trick you might try... go to an art supply store and get a small bottle of clear acrylic medium. (It will look milky white.) Also a tube of cadmium yellow deep or medium hue. Mix just a dab with the medium; just enough to give it a slight yellow tint. You can thin with water so that brush strokes won't show.
Paint a thin coat over your cover and LET DRY; it will turn clear. If it's not working, or it's too much, you can wash it off while it's wet. With a few coats of this mixture, you might be able to get the tint to match the existing inlay. It looks great as it is, but I get kind of manic about these things. :]
