Will do a better render later, this one looks a bit weird.
IMSA Mazda RX-792P WIP5 by ~The-IC. Stunning and realistic visualization of legendary Le Mans triumphant Mazda RX7... Enjoy and don't forget to visit the artist's gallery for more. (
quite impressed by the quality of your work. I think this question is inevitable: Did you took the 787B as basis for this super-machine? Besides, its aerodynamics seems much more refined than the 787B.
On their own, the racing cars are impressive and incredibly realistic. But even more incredible is the road or racing track on which they have been drawn. I love how the yellow lines are scratched and how the asphalt has tire marks. It simply adds to the realism of this awesome 3D deviation.
