Here you can find old car model with compositing nodes setup.
This blend file can be used as test render for cycles performance or for any other purpose.
Please remember that I do not have any rights to free hdr map used in this file (replace it with your own when using commercially)
Where did you get reference pictures, that is Bluprints and/or line drawings etc. where?
No doubt, it's a well modeled car. What doesn't convince me is that glossiness. Old cars shouldn't have that kind of shader. Regardless this, good job.
34.7 seconds @ 80 cycles w/ dual EVGA 1070 superclocked GPUs. Thanks for the benchmark!
It's a lovely car, looks very good, lots of character.
