the concept id great but would still need alot of work before you could pass it off as a finished product, your levels could do with some work to make sure the colors are in the same range, i.e. the beetle seems brighter than the blades and the fairy dust is a bit of an over kill. would be cool if there was an actual beetle somewhere in there albeit small and blurred or something. But other wise I still like the concept well done!
I'd move the car more toward the center, but don't center it. It's so far to the right that the folded blade of grass is the focal point. Nice concept.
The imagery is pretty cool, I would lessen the shadow underneath the car. I'm also not sure about using this as a portfolio piece. I would have to see it in action to say whether it works or not.
good point...I agree with you about the leaning car
