Swim critique (video included)

Ditch the swim trunks and rock the jammers! They create drag. You don't want me giving you form advice!

You come in at 12 crossing your body.  Try right hand enters at 1.  Left hand enters at 11.  Get those elbows up higher.

Pretty dang good for no formal instruction. Good body position, pretty good rotation from side to side. The kick will do fine for now (try to be cognizant of how far apart your legs are when you kick when you rotate, though. You might try swimming several lengths of each workout only thinking about "how far are my legs apart as I kick now while I'm turned to the side?" But I wouldn't work on your kick (for now) any more than that.

I encourage everyone who posts a swim vid to look at it frame by frame. You will self-identify many things to work on. Then ask us re. what some ways are regarding HOW to work on them

As for your pull, you have a really nice bent arm--but it looks like you're trying to sweep something off your stomach down towards your feet.

Try visualising and actually keeping your fingers pointed toward the bottom of the pool, and your elbow pointed to the ceiling, throughout the pull.

Those are the main starter things ... better to tackle one thing at a time.

And welcome to BT!

^^^This.

Also, I think your hips want to sink, which is why you kick so hard. More efficient to keep your hips high by using abdominal muscles along with a light kick:

1. Your hips will be higher than present, reducing drag, thus increasing speed.
2. Your kick will be smaller, reducing drag created when your kick goes outside the cone formed by the rest of your body.
3. You will save your legs for the other two legs of the triathlon.

That's pretty good! I'm impressed.

You do have a crossover though in your stroke - note how your hand crosses the midline on the pull, which leads to a dropped elbow. If you get the arm out more to the side and keep the elbow closer to the surface, you'll avoid the crossover as well as drop your elbow less on the pull. 

You also crossover on the entry when your hand goes in.

Looks remarkably good, though. Importantly, you've avoided the one of the most common beginner problems, which is using an ugly scissor kick to offset an unbalanced pull. Your x-over isn't killing your stroke as much as it does for a lot folks but it's worth a fix.
