I really cant its really good but uhh

Maybe try less fluff? Thats all i can think of, my personal opinion is that if you use too much fluff its just... ew

Smoother animation, maybe a litle nore shading? Other tjan that, its friggin awesme

Anything

Anatomy? Maybe spread the arms out more, thats all i can think of

Only thing i see is the cyan streak across the sky I know its the milky way, but the milky way is white, blends in better, and cloudier looking.

Wheres the shading? The hair moves... interestingly, and honestly all i can see is a cliche half-evil furry oc.

Damn uhh Maybe animate the music notes, even just small animation, it looks kinda wrong if theyre completely still
