Character design is alright, but I think what needs to be worked on is anatomy. The legs look like chicken drum sticks. The way it sways up and down don't look natural, which frankly can be challenging when doing it pixel to pixel. Keep practicing, I'm certain you'll get a hang of what you can do well.

Your OC looks super cute!
I like how, more or less around the second half of the animation, she goes faster with the buttjob, it's a nice touch! The jiggling is right on point, too, so kudos to you for that!

It's an overall simple animation, but enjoyable nonetheless. I really like those kind of works. Definitely gonna keep an eye out for more. Good job!
