hmm decent its definitely semi-smooth try to lower the gap in the beginning and at the end and use smear frames to make look smooth and the head, try to make it bouncy because its the easiet way to make smooth

*easiest

just go up many times as you like (little gap) and down again to the original spot

thats so good i love the bouncy/ transition you did its very smooth aswell try to have little more movement i guess

to be honest meh try to make it smooth

for the first S M O O T H A S A F (its very clean aswell) for the second one its decent

yep

for no effort put into this its decent

bruh

not smooth enough and only the head is moving
