I'm not opposed to stickerbombing, and the gf did a good job, BUT...
I don't think it works great in this application for a number of reasons. First of all, it contrasts severly with the black paint and draws the eye and makes the lip the focal point of your car for no reason whatsoever. Second, it takes a car with a high ride height and the light color of the lip on the black car somehow makes the front look that much higher off the ground. Third, it doesn't flow with the other trim pieces. It'd look more cohesive if you sticker bombed the side skirts and at least the bottom portion of the rear bumper, too, but then you'd have way too many stickers and it'd look terrible, like an art car. This leads me to conclude you sticker bombed the wrong part of your car. Finally, you violated Rule #1 of aesthetic modding: Don't do any aesthetic mods (wheels, lighting, body work, stickers, etc.) until your car is lowered.
I like the idea someone else already posted: keep the stickers on the bottom-most section of the lip but take them off of the main part. That will reduce the intense contrast and allow the rest of the lip to flow with the color and texture of your side skirts and rear bumper. I'd be interested to see how the rear would look if you sticker bombed the lower portion of the rear bumper, too, leaving the rest stock textured black.
