Well, on this one, same details as in the Track version, but in this one are little bit more notorious and several. Can be fixed. Great proportions :)

As it's mentioned above - there's smth wrong with the rear looking - lights, exhaust system... Also the rear spoiler doesn't much to the car design. The rear part of car goes too low... Good proportions!

Front is a bit too square. I would zoom out on your renderings as they draw too much attention to the details, which would need to be very intricate for a close up.
