I love, because this is a contortion act that remains aesthetic. I have no advice to give 🙂
A pefect control of the body (the work of slow motion is great), an impressive technical rigor and you care about aesthetic, in addition this is a suggestive act (usually acts of contortionists always hurt me).
A small suggestion, I imagine a cut on your costume (like cut skirt) to accentuate your long legs.
Very good technique and solid performance. The beginning – I don’t like – not very “Lady like”, but other than that a good performance. Music and costume fit’s her very well. I would wish she would “use” her facial expression a bit more and to see one more trick, others don’t do…she would be perfect!
