Rear bumper mods looks great. but i would try to make the bottom of the licence plate area even with the bottom of the bumper. Stick a plate in there and see if proportionately it looks good. there might be too much room there.
That was my first idea, but then I decided to drop the whole thing. I'm using the extra room for a 12" LED bar as my reverse lights. Gonna tint the whole tail lights red and modify than with LEDs as well. I'll get a Photoshop of the idea.
