GT1 Challenge 2014, Round 1 of Kyoto Ring National. I'm not that good when it comes to Photoshop as my knowledge is pretty weak, but yeah, I gave it a try.
To be brutally honest: Apart from the greyscale image I don't see any trace of Photoshop being used. There could be very subtle adjustments to contrast or colour balance but without starting LFS.exe myself I couldn't tell the difference, because all of these have the same look.
Also a couple of FZR textures didn't load properly (radiator grilles) and your car shine value looks unnaturally low (very distinctive on the windows).
