I like the yellow and the blue as it is. I'm assuming the white parts aren't finished?
Once the white parts have some colour on them i think it will look fine. Only thing i would change is putting a line between the yellow and blue sections to make it a little neater.
not sure I quite understand what you're asking.V you're right it's not finished yet I just wanted opinions on the scheme so far cos at the moment to me it don't look right.
