its the right height, but, too tall too quickly. make it smoother, and less abrupt. make a lil lip up at the back of the wing. and make those supports thinner, and spread them out a bit. maybe make them as wide as the third brake light.
other wise its nice. how does it rest on the fenders? is there some kind of fuzzy material under the wing, so that it doesn't scratch the fenders?
for those that think its too big. they don't know anything ; )
