Overall, very good work on the hair and dress to this stage. I've seen much worse from folks at this stage.
Here's a few suggestions for you:

1. I presume you created the hair and dress on separate layers...? Add a shadow layer for the hair layer, nudge it a few pixels to one side and down, to match the shadow direction shown for the dress folds. You'll need to do a bit of layer masking and a tiny bit of image warp to make it conform to the 'depth' of the underlying figure--ie., where it lays flat against the chest area use less distance between the shadow and the hair strands which 'cast' that shadow, and conversely, more distance where the body recedes from the hair (such as the right shoulder area). Ditto for the fine shadows of the lacing at the throat.

2)You have shadows laid in for the folds of the dress in the skirt area. You also need to add overall shading and brightness to avoid the flatness of the basic color across the entire dress.....since the light is indicated as coming from the left, the left side of the figure and dress should be lighter overall than the right side.

3)Not really sure about that wind-blown side of the skirt hem. Is the dress supposed to be one of those slant-cut things where one side drapes down to the floor? Try to visualize how the skirt would fall if there were no wind, and decide if that's how the dress would actually react to wind. (This one is really a judgement call and not a painting issue....)

Hope these suggestions help. These are just a few suggestions.
