A green metallic paint jobbie could be a great marketing color for all the eco, tech & lifestyle websites & blogs your project will be seen in.
Much speculation on your final flourish. I guess front & rear wheel spat extensions ala-Prius to clean up tire votices. Paint the under body surface areas in flat black, to integrate black rear wheel covers, it also lessens the perceived 'volume' of the tail section. Maybe de rigeur - splitter strakes on the rear diffuser (aero advantage - ?,) but for some cool factor. Also see rear diffuser solution on VW L1 concept.
Good luck on the final model!
