Evgenii Thank you so much for sharing your animation with us!
It looks beautiful overall. I did notice that the movement of the whole body feels just a little bit jerky in some parts. (It looks as if, when the hips shift sideways, the motion gets slightly interrupted, almost as if something is holding it back.) Perhaps the curves between the keyframes aren't quite right in some places. I just wanted to share this observation since it caught my eye.
