shading advice?

Its really well drawn however for shading I'd choose a point of reference of where your shading is coming down/up from.

If you are doing shading where the goes down onto the person i'd draw an arrow pointing in the direction so you remember, the shadig on the chin and jaw doesn't need to be there, the hair shading is perfect and so is the neck. Just definitely next time no jaw/chin shading like that but for the most part you're doing really good!!! I recommend looking up shading tutorials on youtube and following a few of them to get a better grasp of it! I hope his helped !!! :D
