It is difficult to make small cars look interestingly designed with out being busy or cartoonish. It's one of the reasons fashion models are so tall. In addition small cars have less room for aesthetics before they start intruding on function: cargo space, door dimensions, passenger space, ergonomics, etc. Other constraints as mikestew points out: parts have to be useable between multiple cars, small engines and a desire for efficiency mean less wiggle room for ignoring aerodynamics
