heres two sketches, tell me what u think.. oh yea, that 'thing' on the bumper is not an air-intake.. it's the same type of metal-thing that were on the old beetles.. The two things on each side of the VW are indicators..
Overall, they are very nice designs, and I think the starter of the retro "movement" is due for another throwback. The only oddity is on the second one on the Art Deco-esque wing-like grille thing on either side of the VW logo.
To fix the perspective problem, flip the picture 180 degrees and you'll see what you did wrong much more clearly.
