Great work, Jacques.
I've got one small suggestion: I love the range of motion and movement of these poses, but I'm not getting enough broadness of the gestures. Would you please free up and loosen up your lines of rhythm with 31 minutes of 30 second quick gestures? (1860/30=62 poses of figure drawings)
As a result, your lines of action will become even more pronouced like never before.

So, my hat's off to you.
Very vivid work, nice! I like the combination of corvier and straigther lines.
A suggestion would be to look at the lower arms, they are a bit too thin, I would say.
1 minute is very difficult to capture the entire drawing but you've done a good job capturing these dynamic poses. I think one thing you could do to improve upon this is adding a line of flow to make sure that you keep the overall movement together, even if you don't manage to finish the drawing.
