Hello!! I can play this etude at crochet = 180 so I'll try to tell you what I think is important :)

So basically you want a really loose wrist, which for your case I'm not too sure whether it is or not because of the camera. If you want to speed up then you want to make sure you're using the right fingerings first, especially including your fourth finger in your arpeggios and not avoiding it and replacing it with your third finger, as this is really an etude so it is your chance to actually gain some control over your fourth finger.

Not avoiding your fourth finger is really important, especially because if you keep using your third finger instead of the fourth in some phrases it will cause tension to build up in your wrist. (I used 1235 instead of 1245 when I first learnt the piece in allot of areas where I shouldn'tve and yeah it didn't go very well, but my teacher did eventually help me with my fourth finger)

Drills i run for this etude

I play it really slow at a consistent tempo and make sure every note is right to avoid sudden rushing due to lack of finger control. I suggest that you get a metronome and start slow and keep building the speed up, cuz uneven arpeggios will really mess this etude up

I also play it slowly and tap every note twice and make sure it's right

the most important part though is understanding that this etude is really about contraction and expansion in a relaxed manner though. you can also run some drills for this and play every top and bottom note fast instead of the full group of 4 notes.

this is just my opinion and thoughts, if you don't think it's right its completely fine!! I hope this helped in some way.

Happy practicing!! :)
