hey man keep animating, its okay we all learn. work on your timing witch means how long your frame last on your timeline and the key exposure and your spacing, how each frame is spaced from each other. in this animation for peach's body there's way to many frames when you can remove a bunch of frames and adjust the timing and fix the spacing of the frames. because here her body looks so jittery because the inconsistency is up and down, but no weight with how many frames you added and how you spaced each frame out. i hope that makes sense my dude but hope you keep at it animating, i really enjoy the facial expression :)
