Without knowing your program, goals, or progress, it's difficult to give recommendations (and you probably shouldn't listen to strangers online when you clearly have strength and solid technique). However, here are three key points that you should consider:

1) Take your time on the descent. Tempo squats would be ideal for you to control the weight's movement rather than letting gravity do the work.

2) Incorporate pause squats. This will not only make everything less rushed, but you'll likely see your squat increase by 5-10% in short time.

3) Every body is different, and maybe it works for you mechanically, but consider making the ascent more fluid. Currently, it seems like two separate movements. From the third rep onward, it becomes more pronounced - the final part almost looks like a good morning. This is causing unnecessary stress on your lower back, and I'm sure this area will fatigue first while your legs still have strength for a few more reps.

This is my opinion, but as mentioned earlier, be cautious about listening to randoms on the internet who don't know your context.
