I feel the run animation is a little too bouncy? Like I can see that over exaggeration is the key to make something look fluid, but I feel it's a bit overdone.
The way her torso twists from side to side looks good, but when someone is running, their head doesn't maintain the same location, it bobs backwards and forwards slightly

Also for someone who's supposed to be a bit clumsy, I'm impressed she's running so confidently in heels!

As for the umbrella swipe? I think that's what she's using? Maybe a bag?

The foot rising up behind and step forward is a nice little detail! But I think her face staying still for those few frames looks a little strange, along with her hat seemingly bobbling about all over the place.
In terms of the actual swing, I feel it would look a bit better if the speed of the object started slow, and increased as it gathered momentum. Maybe even in the final frames you could add a bit of pixel blur?
If she's clumsy, she might subtly lose her balance a bit after such a strike! Also, her hair is pretty much static!

The idle animation looks a bit overstated as well. She has a very severe twitch! Maybe just a slight breathing animation of her upper body and head, rather than a full bobloop!
