Hm This anim in really good, i’d say make the hand a bit smaller, and where the tear is frowning also a bit smaller since it’s dripping.

i'd recommending maybe makeling the hair a little smaller. it should follow the skull. also maybe make them blush a little or add a few frames inbetween/at the end to make it smoother and longer. your art is so good tho! it's so pleasing to look at it :)
