Too be honest looking at it straight on from the back, at what looks like a standing height, it doesn't look as bad as I thought. The rear hips are definitely wider than they appear which is something I was worried would be lost in the styling. I like the carbon fiber diffuser still. The body colored "bulge" in the back that separates the top and bottom could maybe use some tweaking. Maybe more aggressive lines? The one thing I still have distaste for is the black strip between the tail lights. I think that would look better body colored.
Again, I think this yellow/neon color they chose makes it look worse than it really is. However, I must say the more I look at the car and really examine the details it is looking better and better to me. And I think it needs a small spoiler or ducktail of sorts. That would really make it pop better.
