Maybe if you just kept it black instead of reflective silver and you kept the line the same with the door handles, (instead of being above the door handles) it might have been okay. Almost like the same idea on why euro style tails are really frowned upon (chrome does not make it look pretty). Also, is the original pinstriping still on the car? It'd probably help if it wasn't there (but I'm guessing you used it as a guide to apply the new vinyl).

Oh, and a side note. I do find it slightly ironic that you mentioned that you don't put stupid things like "big ass spoilers" on your car, yet the car you're trying to emulate has a *suprise* a big ass spoiler.
