Well, indeed its very good in terms of anatomy, but:
1.- The hair is a bit to stiff, try giving it more movement and shading to it. 2.- Remark the eyebrows a bit more - it'll give a perfect detail for the drawing 3.- The shirt makes it look as if it was way to baggy, give it a more detailed figure to the waist. 4.- The hands, dear!
And not to say... have you tried doing different poses? It would be awesome seeing new poses for the amazing drawings you do!
I really hope its not harsh ; n ; <3 anyway thanks for reading <3
