Looks pretty good!

The modeling is pretty solid. The texturing could use some work. The Ferrari paint looks like plastic, so in the other images it looks like someone took a lighter to their toy Ferrari.
With all the melted/burned areas and such.

The paint texture you are using seems pretty good, but you need to get rid of those orange highlights.
Plus a few more photons in your scene wouldn't hurt.

Over all, really nice work!
