Wow, Must admit its a very varied selection, I agree with what looks like too small mirrors on the fiat. Not a bad idea to have a chronological render of your models... i should try that.
I would say they all look well for only 10 months use, and i suggest in another 2 months or so go back and do one of them over again from scratch, i have gone back and done a 350z 3 times. First, then 6 months later, then another 6 months later, you would be amazed at the new ways and streamlined methods you will gain in that time. I could probably model that one car well in no time now because of the learned problem solving.
I wish i could help on the rendering though(mine always blow...).
