First of all, your pushes and down movements are excellent. Very strong and fluid.
When I watch that video, what sticks out is that you aren't setting your feet. You are constantly moving, even when you don't have to. For example, the first goal. you come out to create depth, then immediately start to back up and give some of it away, and move off your angle. The puck hadn't really moved much so there was no real reason for you to give up your depth. I know you were looking through a screen. But you were in the right place, and moved yourself out of it on your own. This happens a lot, if you look closely. Find the angle, create depth, and set your feet. Make small adjustments as necessary, but always get to the new spot as quickly as possible and set your feet again. Snapping your heels into place each time you adjust is a good way of getting set up. Even shuffles and t pushes should be a series of distinct individual movements, start-stop, not one long one. When you are in constant motion, it's easy to get off your angle, or lose your net, or depth. You lose some efficiency in your movements because your weight may not be set, and you may be a little slower because you have to correct before you can move. Rebounds and saves are a little harder to control because you are maybe a little slow or having to readjust to the shot before moving. Just my observation.
