Very nice work, but the others are right on the critiques. I myself love classic Ferraris from this Era. Especially the 250 SWB GT styleS. Anyhow if I have time later I'll also take a crack at critiquing this car, but I'd have to refresh my memory of it with some pictures again.
The roof is a bit flat. Headlight covers are better, but you're not done yet : they should be more bulgy I think (the right one looks OK, but the left one still needs some more relief - left and right as seen from the car)
It's time to add some details on bumpers (screws or anything else to tie it to the body), on tire sidewalls and so on.
Only one more critic : the reflection on the side are not as smooth as one could expect : the transition between black and white (once reflected on the paint) is wavy.
