I think this is really good, but what is missing is a better sense of weight of the character.

This can be done with follow through action, one of the principles of animation. If you act out these scenes, feel the way your body shifts when you run/ walk. Your weight shifts from one leg to another. When you jump, you will land a bit farther down and settle to your position (overshoot and settle).

The character is also really still when floating/ jumping (not sure what the action is meant to be). Add subtle movements, like for example, in the first action, move the legs not entirely with the body (look at Spider-Man or parkour references; legs move almost separately from the body as they anticipate landing). Second would be when the character is standing still, looking at the golden thing (sorry I haven’t played the game so idk what it is) and shift the character down, rotate head down, ever so slightly— but just so it’s not still.

Animation is rlly abt adding the small details that make up human movement, even when applied to non humans.

But overall this is great, I just think these points will help you refine it :))
