Ok, thanks that helps a lot. Her nose is off center to me. Her eyes are too symmetrical in the finish, but you created more of a turn in your overlay. The lean forward is not reading as clearly as it could. That could be the angle the pose is viewed at as well as creating more deep folds. Perhaps deeper shadows below the bust as well to accentuate the lean. I actually like the pose. XD Go figure.
Those frills! They're lively and very cleanly sketched- feels like she's in motion. The texture on the fabric is really interesting- you've added a subtle shine that works very well in the scene. Skin tones are tops, too.
But what I really like about the picture is the overall sense of motion conveyed.
