Saw some of the unjustified ratings; down voting/up voting because you like the show, not because of your skill.
I like the shading a lot, and I like how some areas are sketchier than others which makes it look out of focus (whether that was intentional or not). My only gripe is the neck because the direction of the shading makes it look like her neck is stretching (only the direction, the darks and lights are fine). The background is also pretty bland, wouldn't hurt to have more going on (a window, a table, a mirror are just a few ideas).
