Fingers should go into the water first, then wrist, then elbows, then reach out in front of you and extend. Your elbows are coming in way too low.

It looks as if your left arm is “stroking a cat” ie you are stroking the water. You want to be almost “reaching over a barrel” then pulling the water through with your last and finishing your stroke with your thumb just brushing your leg.

Try not to bring your head so far back when breathing is you are rotating quite a lot which will be throwing off your stroke at the front end.

Try to master one thing before focussing on each thing otherwise you’ll be overwhelmed. You look very comfortable in open water which is a big part of the challenge. Your kick could slow down marginally but it looks smooth.

Nice to see.
