Beautiful!
As you mentioned in your PM, I realize it is still a first draft, but have the following creative suggestions:
The size of each of the cars should be more to scale...for some reason, smaller cars seem bigger and bigger cars seem smaller in your artwork above.
The Esprit (especially Stevens model) should not be smaller than the Elise/Exige. I suggest that the Esprit be the size of the Elise/Exige in the illustration above and vice versa. The Elans and Seven look larger than life too...or perhaps maybe just the Esprit needs to be a lot larger.
The font should definitely be a little more aggressive and exciting...in the very least more prominent.
Anyway, not complaining...just trying to help for the benefit of all...either way,
Good Job!
