Great stuff. It looks very real. I am amazed at how low poly your model is in wire and yet it mesh smooths so well. I have two small crits:
-The paint material is really cool, but on the edges it gets white and it makes the car look kind of dusty. It might be a falloff material that is set that way?
-For such a shiny car I would expect newer tires or at least a cleaning with some ArmorAll. I would suggest maybe shining the tires up a bit.
Great model and great renderings.
