The intervelocity sticker is probably annoying because it's white. I could see it looking better (if you must rep them) in silver to match the car or a dark grey, that way it "blends".
That Kenwood sticker has to go though. Kenwood isn't really the top name it was in the early 90's.
Other than that, the car looks fine. Everyone has their own style.
If you wanted to do stickers you could go the traditional manufacturer names (including velocity) down the door 8" wide and all black or something.
