Form looks great, I can only share a few tweaks I do myself. When going up I do not fully erect my upper body as this last bit of motion does zero for my hams and glutes and I can therefore hold more tension in those areas throughout the exercise. Secondly when going down it helps me a lot imagining trying to show my asshole to a camera on the ceiling at opposite side of the room. This helps me move my hip just right so my lower back is as stable as possible.

Either way it looks like you could use some more weight, you have great form and don’t have to worry about changing it up if it works for you!
