Those unknown sprites look better, you did a great job on fixing up chuchoryu's-uhhh-sprite art. But if I can give feedback, the crouching animation for Unknown looks choppy. Take a look at other CvS characters and how they crouch if you want to get a better idea on how it works.
The second animation is perfect, I don't see anything wrong with it.
Keep up the hard work man.
