Where are her arms? Why is she wearing two skirts? If you're going to make the fabric of her clothing translucent, you can't hide her limbs at the same time. Either make it opaque, or learn how to draw bodies instead of deliberately hiding them behind poor design. I recommend the latter.
Why do the wings hover over her hair? If they're emerging from her body, her hair should fall around and otherwise be moved by it. The way you've drawn it, there's no interaction between the two at all. They're just there.
The folds in the dress are dog shit. Go get a kind of fabric with a similar material to what you're trying to draw and drape it over something (or a reference picture from the internet). Observe how the folds form and fall. Consider its weight and gravity.
