I would change the base cape frame, where it's laying flat as though there's no wind, to be another billowing frame. It sets an odd rhythm having it there - when it billows, it should be whooshooshooshoosh, almost, whereas with the base frame it makes it whoosh-dum whoosh-dum. Apologies if that sounds nonsensical.
Additionally, the frames where the edges of the cape flip feel a little awkward. Some of the pixels feel like they're stray, almost, especially in the hood when there are two pixels just sticking out. Here's a rough edit, which admittedly feels like a less violent breeze, so you may want to keep the fuller flip at the edge of the cape.
