>>47236790pretty nice spritework in general anon, good work,
the last frame looks a bit abrupt, particularly on her hair, other than that the heart(?) mark on her ass doesn't move with the rest of her body properly, I know it's a 5x5px mark and it may be a bit tedious to make it look right, but if you want to make it look good you need to deform it like her hair to go along with movement
