Well, I kinda like the front end. I made some little changes in MS Paint, so the quality stinks, but you get the idea.
Of course these would come down a little farther towards the ground to line up with the rest of the kit-I just don't have that light lime pearl w/flake in my version of MS Paint
I have no problems with the side skirts. Although the car they occupy...
The rear bumper is the only piece I don't like. The front is a lot smoother and simpler with out the death blades on it, but the back still looks like a Transformer. I think you're really on to something with the rest of it, though.
