Mike,
I think you can better see the undesirable spots (frequencies of light?) In this close up:

The photo shows some colors and details that are not so prominent in real life. I think the oranges and violets seem to come out way to much. The tiny hairs are too hard in the photo, opposite to the real painting in which you can barely see them (please go back to my first post and look the photo taken with my hand in front of the painting. See how her face looks smoother with better transitions than in the other photos). Yeah, I know I may be asking too much from the digital world, wich I agree with you is remarkable nowadays. I just started this because I'd like a representation of my painting to be more real and somehow I believed the fact of adding a real skin tone in front of the portrait made it look closer to the way I see it.
