Smooth animation, you’re already off to a great start !

The background lookin sad right there, c’mon it deserves better, like a rocky ithmus or a cliff

You should improve on camera movement, it’s a pain for me but maybe it isn’t for you, fight scenes will look much more dynamic with a moving camera

Camera placement is also important though that means you basically have to do 3D, and only a few psychos can do a 3D effect on SN

Also 2 nitpicks I have : the colors, it looks outright weird , there’s also hardly any gradients on the characters, or anywhere, and everybody knows gradients literally makes everything look better, but those are just nitpicks.
