you've somehow made what was a very pretty car into something resembly a tacky limo! i really don't think the fisheye is the best sort of lens on this sort of subject ;at least not head on. it does have the benefit of looking like nothing else though! i like how sharp it is, and the clean whiteness of the car really shows between the sky and paviors. the sunlight on the left is far too harsh, though, and the building on the left and the red car on the right distact some. as does your reflection! 6.
To each his own here I guess, but this just doesn't seem like a very good choice of subject for a fisheye image. Maybe it would be better from a front or rear view?
