Long time no see...
The #2683 sketches are really close to what the eye needs to see when you look at a very lively scene, with lots of movement.
You developing is interesting through the last pages.
I'd focus more on the lines. Try to draw with less tension, as about the outlines at least, so you could make the outcome more dynamic with lost of different kinds of lines.
It's also good to see that you are dealing with various materials and project without loosing your focus.
