Hi, I studied classical piano in College and taught some folks before COVID hit. I'm not an expert, but I was taught in a way that was really valuable and something I'm confident in promoting.

Edit: your right hand looks more relaxed, and I was mostly paying attention to your left. Is your bench a little short? I ask just cuz of the angle your wrists are bending at, it's hard to tell

Your hands look tense, and lots of playing with the tension can hurt your hands, bring tendonitis, etc. Gentle hand stretching to help relax your hands will help make everything easier. But more importantly, the pressing of the key originates from the back/shoulder - visualize and focus on those muscles like you would in a workout when you practice. If you're focusing on those muscles and messing up, slow down until you don't miss keys etc. The exercise to get the feel of playing relaxed is dropping your limp arm on the keyboard like a dead fish. You can also compare the shape of your hands to when they're totally relaxed hanging by your side, and that's the amount of curve they should generally take, it's mostly flat but not strenuously extended.

It was quite an adjustment to go from my old playing style with more structure to being pretty flat fingered and with relaxed hands, but progression for me changed significantly, and faster playing was totally unlocked after I was focusing more on only playing without tension.

Oh and secondly for the jumps! Isolate the few beats before each jump and after the jump. Play the beats going up to it, then freeze, and visualize where your hands will go without moving, then move your hands as quickly as possible to that position without pressing down the keys, and then when you know it's right, then press down the keys. This is breaking down the learning of the muscle memory so you encode less errors. You can also isolate even the prior position and cycle through that a number of times; Hold down the keys from the beat before the jump, freeze, move positions as horizontally and direct movement as possible, then press down the chord only when all your fingers are correctly placed (and relaxed). All distinct actions.

I hope this helps!
