What I'd like to see is you tackling the next level of detail (pick a car, any car). Some of the models (especially in your funny scene with cars in the wastepaper basket) look kind of promising, but I think it would be more interesting to see one car done a little bit more precisely, tacking things like bumpers, grills, and so on.
Car modeling is tough. I've had little success modeling even modestly detailed cars, but I created my own low-poly car factory some time ago, for a game I never got around to coding.
