At first impression when looking at the little thumbnail, I thought this was a photograph...only to find out that the perfection in the lighting of said subject was found through the maestro touch of someone with talent and a brush...made it all that much more delicious to gaze upon in it's full splendor.
Great composition. Love the lighting, your extensive use of light and shadow, the intense brightness of the hair contributing to her facial skin tone. It's very interesting and really deserves the DD. I congratulate you good sir!!
