Swim Help

I don't know if you breathe more when you're doing a long set, but in this video you're only breathing every fourth stroke and that's a lot of holding your breath. If you tried running and holding your breath that much you wouldn't be a happy camper! I would try bilateral breathing which also may help out your balance issue which is the probable cause of your legs scissoring out a little too much sometimes. If you have more air, you'll be able to keep your form a lot longer at a higher pace as I suspect you get pretty winded after a few hundred yard (metres?) if you are indeed only breathing every fourth for all your swimming. Personally I breathe every second stroke, but that's what works for me.
If you're not comfortable breathing to the other side, do some sets where you breathe only to your bad side, you'll get used to it and then you have that as a backup plan if you're in an ocean swim and get battered by waves from your good side.

Looks like you have excellent flexibility in your ankles and should really fly when you get those smaller things down that others have suggested.

Cheers,

Mike

I looked at the video a couple dozen times.  I agree with the other posters.  The only things I would add is that your Right arm seems to stab the water just above your head and then reach out underwater.  It might be nice if you could reach out over the water a little further.  And your body roll is very strong on your breathing side, but a little flat on your off side.  Bilateral breathing may help, or else just some body roll drills.  Overall, looks good for someone only doing 4 months.
