Wow, awesome way of doing things, I also like how you increase detail, rather than Depth Of Field it's like a Depth of Detail. Very cool, your angles are well done and the concept is just stunning to me, nice job!
Yea your right it probably is a little long. The people that I did these for wanted really forced perspectives so I tweaked them quite a bit. I guess this style fits the 60's era muscle car though. The old adds in magazines had this look sometimes.
