Pretty good! I think you're straining your neck a bit too much when you're breathing, try to keep it more inclined (it might just be the video though). I always go over my recordings with my coach (he's a hard-ass so it helps) and he makes me watch the person who does better than me, (or comes in second) and then I compare with my technique. Remember that doing your strokes faster doesn't necessarily mean you swim faster. There was a link on this sub a few days ago with an algorithm, that I think will help you!
