Nice job in the hair but i think its too spongy to the sides.
The marks below her shoulders are too marked and should be more light colored to make the difference that theyre not as marked as the neck ones and the neck ones were to below should move them a bit more up.
Her shoulders are weird... should make them different (Up to down)
The mouth was nice but is there a missing line there? change that.
The nose is move a bit to the left and should be more on the right and up and remade the shadows.
Apart that, nice coloring, nice eyes, nice head shape, gj!
