Man, the quality of them is unbelievable! The first shot, though fairly simple in concept, is perfectly executed! For some reason, it makes me think of an old European movie.
The Amuse GT1 is awesome, too. The reflections are great, I'm glad you didn't went overboard with them 👍 You even choosed Nürburgring for it, too! Can't make this pic any more better than it already is 👍
The Ford GT has an excellent motion to it, almost makes you feel you are there, seeing it drive through the streets!
The last two pictures, though
The Tommy Kaira is brilliant with that paint scheme, and the spoiler and rims look so real! I would bet you transplanted the wheels from somewhere else, right?
The last picture, however, is in my opinion the most enhanced of them all. It looks surprisingly real, but at the same time, it seems to have some sort of cartoon feeling to it.
