Hey guys, check out my latest animation called The Tremor
You know the drill: Please give pointers and advice and don't hold back, no matter how mean it sounds, stuff like this helps me to improve a lot! Thanks

Is that guy's spine made up of a spring?

Your Problems are: Spacing, Easing, Choppiness, Stiffness, Physics....
Just keep making more animations, and dont forget to check the tutorial section often.

The framerate is too high, try to keep it at 16-20 frames per second and you'll be good.
The stickmen are shaky and hella stiff too.
You should ease the movements of the stickmen more and watch the footplacement.
I may recommend you to read the tutorials, watch others' animations and practice a lot.
Good luck and have a nice day.
