She is one of the most beautiful people I've seen and you have captured her looks very well. I recognized her immediately. The shading looks soft and natural. The only "weak point" is to me the spot where her hair meets with the neck on her right side, I think it merges a little too much with the neck and you cannot tell where the hairs end. Anyway: It is an amazing drawing!
"I had to try and capture her beautiful eyes again..." - captured not only the eyes "My bad, cheap scanner did not catch all the details though. It looks smoother and "warmer" in real life." - if that's true then I am even more impressed! Well done
