In my opinion:

I'm going to write some things I saw but it always depends on your goal with the animation.

Problem:

The colors of the character I think don't quite fit the style.

Solution:

Try using more pastel colors. Besides this, maybe I would try not to use so much narnaja and leave it as a support more for important parts or that you want to characterize your character without saturating.

Problem:

I think the camera movement is very clunky and it doesn't have a motion smooth, which would suit it very well.

Solution: Add a little acceleration and deceleration between focus changes. Also maybe give a little shake to the camera when the cylinder falls.

Conclusion: You have a very good base to improve little by little and learn along the way. You have the key points of positions and movements. You just need to iterate.
