Mac - I think the cream panel works pretty well with the sweep around the rear arch staying in blue.
The only thing I'd be tempted to change is paint the vertical "lip" at the bottom of the body shell black.
That would help it "disappear", whereas currently your eye does get drawn to it due to the contrast of the lighter colour against the ground.
What are you going to do with the "spare" front indicator holes?
How about a mesh vent like on this MEV?
Good luck, Paul.
