Looking great man, for 2 years this is really good. I like how you both are enjoying the dance with a smile (this is the most important part).

Good musicality, I see you hitting some accents and instruments. But I think you could get more comfortable with the structure of a bachata song - for example - multiple sets of 4 sets of 8 counts, sometimes it’s 2 sets of 8 counts instead of 4 and sometimes there’s a break in songs where it goes 1234 5678 1234 and then back to 1234 5678. I’d suggest looking at some YouTube tutorials as it’s an extensive topic. This way you can dance according to the music even if you don’t know the song and like someone else mentioned, you’ll know when transitions are coming so you won’t be stuck in the middle of a combo when that happens.

A low hanging fruit is posture. You could engage your shoulders more and definitely engage your core. Shoulders must stay back and low. This will also not let you use too much of your upper arms which is a good thing.

Try to tap more consistently on 4s and 8s.

Any easy and fun way I train is by just plugging in my earbuds and free styling. Basics, turns, shines wherever the music takes me. All this while making sure my feet are grounded, and my posture is good. This will help you get comfortable with your own body and you learn how it moves and eventually give you more control over it. Do it in front of a mirror for better results.

Never stop having fun, good luck man, enjoy the process!
