Tomasz Bazylinski I don't know what is wrong with this people ;D Thanks for tip!
Kamil Grzegorczyk if you manage to reduce saturation on reds and a bit of highlights please share your results. It is always good to learn something from the others - this is why we are here - and I wonder what could be your final effect;)
Kamil Grzegorczyk At least once my car is on the photo, but why this stinky yellow guy is trying to touch it? No touchy-touchy!
P.S.
Did you tried to reduce the highlights? It would give less "plastic" feeling.
