(you posted the link bad and it didn’t embed you should feel bad)

but
since it’s a test im gonna tell you how to make it better

basically, add more frames in your movements
you’re actually really only animating the literal key frames of the movements

arm up, then arm is down – …what happened in between?

turning on tweening would prevent this but it’s not good to rely on tweening to do *all* of the work for you, even just one extra in-between frame between your movements (then turning tweening on) would look 10x better
