That's a great result, wheels and all, I love it. In fact I like the wheel colour so much I'd be tempted (if it were mine) to add a bit more blue either on the belly pan or along the lower edges of the black panels. Or perhaps some blue accessories to pick up the colour in the stripes.
I did think about adding something to the belly pan but decided against it. Unless you're laying on the floor looking at the bike side on then you really don't see much of it and I certainly wouldn't paint it for the sake of painting it. Knowing when to stop is a dark art.
One of the admins over at Boxertrix has offered me a couple of their site logos. I might just use a couple of those carefully placed instead .
