i made a paper model of a little hatchback once .....it was.....very ,very bad so i put some black cats and firecrackers in it with the help of my pyromaniac friend and watched it BURN! i like legos better.(oh, yeah your model was good too..)
I think this model needs a work on its side profile. Like moving the A-pillar front to give it cab forward look, and slim the lower portion of the car by adding more ground clearance.The front and rear end look fine though.
