I'm surprised you want to change the bike at all - looks really good!
That being said, do you have a burning passion for anything in particular?
Big Ducati fan? Music bands? Sport? Dungeons and dragons?
If you can think of something that you'd like to dedicate the new fairings to, we could all probably help you figure out a design. I probably wouldn't suggest dungeons and dragons, though, kinda lame
Otherwise, pearlescent/irridescent paint jobs always look mind-boggling!
