I agree and also I think there should have been a canard that comes off the sides and that the rear piece should come up to meet the curve of the bumper. Also the attachment points should be on the bumper rails to hide the hardware. I think the guy from HTAuto's said it was near impossible to round the edges but yeah I think this could be better as well.
