Nice job on the proportions..
A side note, maybe it's just the lighting you used for the snapshot, but her complexion is a lot paler than it should be. There is also her eyebrows, which in your snapshot appear to be outlines rather than solid
Looking at her image from the show..
And then comparing the palest point of visible skin to the palest point of her skin on your version...
Well, side-by-side, the contrast is rather stark.
EDIT
I tried editing your screencap to make her coloring closer to the show, and this was the result.
