No dissing here.
The thin bumper is a great idea but the one your mocking up has a slight inward curve to it from the end to the peak in the middle.....may look better with paint but looks a little out of place as it sits....like a mustache on a girl.
Could be my eyesight but it's not 100% awesome....like the rest of the car.
My opinion is always questionable. :D
Keep it up it's looking sweet.
