This looks rather nice! The shading is pretty decent, it's not much, but it's in the right places (neck and eyes)
Her head shape is a bit off it's symmetry.
The hoodie part of her jacket looks a little small, and I agree with Caniac76, her hoodie has a lot of negative space since it's large and empty.
4/5 stars, there could have been some things fixed, but still a high rating thanks to effort and time you put into this one
