if they are sponsors cool, if not take the darn stickers off
and if htey are sponsors, the headlight cover aint a good spot, it just doesnt flow. try your rear side windows (the triangle shaped ones) stickers look pretty good there. The wing, really I dont mind it, its not a flamboyant double decker aluminum one, it looks ok to me. The front bumper is a lil gaudy for my taste, but then again I personally like the almost stock look, but its not too bad. Your car is tasteful, I just dont think the stickers are necesarry :P
