Many European countries have strict laws about pedestrian safety which may have much to do with the current trend to upright front ends. However, car companies are now radically curving the sides of the bumper toward the front wheels at the same time.

IMHO if you can get your car to look closest to the Impact concept, the better. So, smooth, gently rounded is best. Post a photo of the finished one?
