Very beautiful! Similar to what Steve said, I do have a few suggestions for you to consider, if you are inclined to continue working on this piece. I did a quick paintover to better explain, but it comes down to the distribution of light. There are some areas (nose, cheek, jaw, blindfold) that would receive stronger light, as well as some areas that are more in shadow (neck, ear, flowers). The nose and neck would also be softer with less detailed anatomical definition, either due to the light or more typical female anatomy. Also, compositionally, I reduced the value of the background near her eye/nose area slightly for better contrast and moved her clothing folds to create better flow. These are elements you can continue to play around with to see what you feel best communicates the readability and message of your painting. Either way, great work :)
