I'm in the camp that Fran has nailed every design angle for the S, X, and the 3... Except the nose cones. For me, that's the weak spot in each of them. I can get past them as the cars are so awesome in every other way, but our input here can help influence Tesla before they finalize, as each model's nose went through several iterations before final production.
I know the nose cone has huge impact on aero, but just as easy, very minor changes can also have huge complimentary impact on aesthetics too, while not compromising drag.
