Front squats look real good.
That's the same water bottle I have.
Back squats look ok, you start shifting forward as you get tired.
Snatch grip pulls look good. Look at your second set at 175--there's a point at which after you get your back tight, you start the pull but the hips go up first until they lock at a certain angle and then you break the bar off the ground. That's wasted motion.
Once the bar leaves the ground you do a great job of not letting the hips rise first, so it's a clean lift. But your set-up may benefit from getting DOWN to the bar instead of UP to the set-up. I mean, basically bend down and grab the bar in a stiff-legged position, set your back, then pull your hips down and back into the start position, then pull. This instead of sitting down, squatting at the bar, grabbing, raising your chest, and going.
When you do the latter sometimes you leave your hips too low in the start position and they rise up as in your set before the bar breaks the ground. You lose tension and you struggle more off the floor when that happens.
As I said, your actual pull looks just fine. Your mileage may vary as well, some people are just uncomfortable with the set-up I described.
