I adore the cool and warm tonal range through out this piece. The small sparks of fire carry the feeling of fire crackling throughout is a wonderful detail. I love the way the wall reflects the tones, and captures the lighting of cold and warm.
I think there should be however; more cool tones through out the top of her head reflected from the crown, as you have made those lights bright and vibrant as well as orange glows on the chin and back of hair.
Overall this is a gorgeous rich piece that is well done, with great technique!
