I still have trouble getting this to look right. Here's the PSD for the attached image:
https://www.mediafire.com/view/kgn4wbc8jjcujq7/PhotoshopR_Greenberg.psdThe most important part of the hyper-real or "painterly" edit is the work with D&B on the transitions. You have to simplify the transitions/forms of the head while enhancing depth. it's time consuming. As for the color, seems like cyan midtones, desaturated highlights, but I can never get it quite right. I'm sure I use many more color layers than I need to. Lots of great advice in this thread. Hope the psd helps.
