looks terrible. the front end of the bumper is mostly curves and adding a lip that is done mostly in angles doesn't flow well at all and really looks tacked on.
So smooth out the center, lose the gap in the very center between the lip and the bumper, lose the area right near the opening where it juts in and just make it one smooth flowing piece across there, smooth the radius's to match the contour of the front bumper and you have a winner in my book!
I think I said smooth 100 times!
