The biggest problem with your front bumper is the fact that the openings do nothing to wrap around the front of the car; they are simply muscled straight out to the front, leaving the sides too plain, the front too blunt and the car looking very awkward, non OEM and frankly like its got its cheeks full, ie:
Lowering the height of the side openings and extending them towards the sides of the car would have a dramatic impact for the better, IMO. I also don't see the point in losing the OEM side markers/fog lights; lowering the front opening and incorporating them into their stock locations would help a lot as well.
