This is just so cool! I love the painterly style on the hair and the stars you see in the darker areas.
It's nice to see a nude female that is not nude for clickbait or, well everyone knows what reasons. I also love the way the shadows work around the body and the simple but effective line work. Just one thing, I do miss some detail at the toes, looking at them, they seem a bit awkward, also the ear could use some (thick) line work to make it pop out more.
BTW: Nice yellow mark she has on her forehead, really makes the piece complete.
