The shadows should follow a very similar format as well. Use sharp nodes at the tips, and only use the handles at each end of the tip to shape the curve. The shadows are also not lined up very well and are overlapping in a couple of areas. If you are using Illustrator, you can use the Shape Builder Tool or Smart Guides to make the snapping process much easier. If you are Inkscape, then you need to align it manually and very carefully.
I went ahead and did the hair to show you what it can look like. You can ignore the shadows that are supposed to be under the bow.
