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 :)

Wow. This is beautiful. Did you use a reference?

Hey Nick, This is really nice, good job. I have two really subtle, nit picky things to mention: The edges of the nostril and the ear are so hard they draw my attention. And, the contrast of the shirt and hair is the greatest in the painting, thus drawing my eye there first. I did a quick change to it just to show you what you might do to address these things. They are very small so you could take it or leave it. Hope it helps :)
