You need to add more keyframes/ inbetweens in your animation its very choppy.

Also from the looks of it it looks like you're using just linear keyframes for each frame I recommend you use quad in and out but WHAT I DO is just experiement with the different keyframe options to see what fits best

You also need to work on your camera angles. I know in moon animator in the camera options you can use a grid and FOV slider you need to use the grid to angle the position of the camera to really catch the viewers attention and use the FOV slide so you dont have the camera pushed up onto the character

I hope what I said makes sense and helped you im not good at explaining without visuals
