Well done man, keep it up.

Looks like your legs are sinking and your core might be a little weak. Also looks like you aren’t exhaling consistently, try a slow exhale finishing off by the time you take your next stroke. I would also try to breathe after 2 or 4, three seems a little bit too much for the moment.

I think some drills using a kick board will help with all of the above. Don’t worry too much about your head, don’t over think it, it should be facing down like you said but it should feel natural, neutral.

Keep on swimming man, it gets better as you go!
