Looks good, not sure about the color scheme...its like it wants to be flat, but maybe you desaturated everything but the motor and window refs on purpose? Feel of the image is great, but something is throwing me off...cant quite pin it down.
Anyway, looks good. Like the style, open bonnet looks hawt. Bumper donor looks familiar, trying to think where I've seen that before.
Keep it up

Good luck in the comp.
