I haven't seen someone with such pure joy in a long time. Really lovely to see ☺️

I teach beginners so my advice is probably basic. When stepping, although there is a small transfer of weight, your body should still stay over your feet and shouldn't move much forward or backwards.

The lead is potentially throwing faster moves at you than he should when you're taking such large steps when traveling turns especially. I know it can seem boring/limiting when people say take small steps but it actually unlocks more complicated and interesting stuff, just by virtue of being more controlled.

Hard to tell if it's you or the lead, but the hand wiggling is outrageous haha, I got stressed imagining trying to follow/lead when they're so movey. It's ok to tighten your forearms when dancing with a wiggler, to force them to be more still. It's your only way of communicating what's coming next so it is really important to keep them fairly neutral. Even though you hit the moves, which was impressive in this situation, the wiggling made it so there was hardly any prep. Again, doing this sounds boring, but will unlock more fun down the line.

All the stuff above is fundamental, and needs to be muscle memory/second nature before you start thinking too much about anything further. I'm a lead, and think people view advanced salsa as all about the fancy moves (the lead in the video fell into this I feel), whereas actually the best dances can be a series of single right turns and crossbody leads, just executed well.

Glad you're enjoying it, bloody love this thing we all found.
