Uhh, taron.
You think it needs some feeler

Thanks for the input. It was quite a ride, but worth it.
Eduardo- you mean you would like to have an impasto tutorial?
That would take some time. Would be good for the „everlasting tricks“
I‘ll try to make a preset. No time for detailed explanation.
Anyway, I am not there either.
One thing always worth to play with is light.
Put layer bump a bit higher, around 50-max
Brush#2 is more structured and easier to adjust.
A bit more build up in brush parameter, sometimes a little bit blending in brush parameters to soften a little bit.
Light controls are:
Shift+ Arrows and Shift + page up and page down for Z axis can help a lot.
A little bit of metallic in the level parameter is looking like ambient occlusion, that means shadows looks more emphasizes.
