you have good ambition which is a good thing to have because it forces you to be creative

just gotta work on the execution, pay attention to movements, all movements, try to mimic real life when you’re animating, think about how actions are performed

a quick example of what i mean
when he stands up at 1:04

he doesn’t really “get up”
you just kinda rotate the stickfigure and move his limbs in place
you don’t even respect the position of the floor, his feet end up much lower on the screen then where he was lying

think about you, getting up off the floor
you get onto your hands, knees
put a leg up, shift your weight upward and extend the legs
you need to * animate * those movements

this the one fight i think i would actually say Superman would probs win

animation tips:
move more than just 1 limb at a time

pay attention to flow, things/people don’t just stop moving in mid air or some to a sudden stop when it’s time to animate another character

in a dynamic scene like this, don’t just shift the camera around with no purpose, keep it smooth, zoom in and out where appropriate/etc
