Nice work on your quicker 30-90 second poses, that's the way to go.
Again, I feel a little bit of rigidity in some of the LOA (Line of Action) quick gestures. Why don't you please work on giving your lines and forces more than enough freedom of organic lines and shapes, thru 60 minutes of 60 second poses??? (60 drawings)
The reason why is because, it can help you out on not only your drawing quality, but on the overall speed, and inherent output, you know?
If you wanna and need to see more of this, look at that link: https://www.google.com/books/edition/Animation/R3VYtdXCGTMC?hl=en&gbpv=1&bsq=quick%20sketch%20exercise It has an important exercise on one, that's extremely useful to your creativity and artistry.
So I say, good luck, and cheers to you.
