I really like your sprite!

For the animation there is work to do.
- The left arm disappears completely between the first and last frame which makes it seem jittery.
- In frame 1 4 and 5 it's really hard to tell what is going on with the arms, the shapes turn into something unrecognizable.
The arms seem dislocated from the shoulder. It's like the shoulder is attached in the middle of the chest?

There is also some inconsistent arm thickness.
- In the 1st frame the line on her stomach almost looks like an additional arm with a hand. I think this line also messes up frame 4 and 5,
You have a lot of work to do when it comes to making clean and readable arm shapes. Start by maybe making the entire arm up to the shoulder a completely different color, like Purple. Then work on getting that shape looking fluid. When it looks fluid, then you draw the clothing.
- The shoes look a bit messy.
You could make the left arm significantly darker to make it easier to tell the arms apart when they go back and forth.
The legs aren't really fluid but I don't have any good insight here. It's easy to tell their shape and tell them apart though!

I think the hair is ok, maybe the hair on here head could shift slightly, but that might also make it look like jelly.

The skirt could have more fluid movement though, which I think would help the overall impression.
I did an edit for the sprite. You have a lot of similar colors and the hair/face blends together a bit.
Tried reducing color count and increasing the contrast. Removed a bit of banding.

Anyways, it's easy to point out flaws, but it's much harder to actually make something from scratch! So keep up the good work.
