Looks like you used Speedracer1983's Team 75 Bernhard Porsche from his ADAC GT Masters pack here, at least many of the items align perfectly with each other.
The Skin Map doesn't match the Skin (for instance top numberplate on the bonnet instead of the roof). blue line is very jagged at the tail portion.
KÜS logo on the doors is too large.
As I love this specific Porsche, I hope to see a complete makeover with a stunning result :)
