Yah that is really nice work, i've never had the patience for Illustrator - then again I'll spend 15 hours on a pencil drawing. go figure.
There is something a little off with the perspective that my eye keeps coming back to. I'm not sure if I can pin it down to one thing though. It may be the angle of the grill in relation to the headlights, it's just a fraction off. I feel like I want to rotate the healights just a touch back into 3 dimentional space - I'm not explaining this very well.
I do like how you balance the heavy left side with the open space and lone headlamp on the right. Good use of composition.
Overall nicely done.
