Karina and I did exactly as we planned, so we came away extremely happy. I hit every beat. I didn’t hear any specific comments about not leading with toes or having toes pointing wrong, or a hand upside down, or leaning forward, or having a foot miss even a single beat (it didn’t happen). All I heard was some teletubby comment, which might be valid. I would say that there is a big mismatch between the judges’ votes and the audience responses. That might be a matter for the producers.
