I think the structure of the drawing is very good. However, the drawing does not look finished.
Toward the end it just seemed that you were in a hurry to finish the shading and the viewer can tell in the textures.

With some more time, it could be a nice drawing. All the elements seem to be in the right position.

how tanner said it loox like it is not finished,,i think eyes are way more darker then the other part of the face which should be darker is well,,i would put more effort to work out the details in fabric on her shoulders and the hair need some more attention in dept,,no criticism only opinion..in overal nice work
