It looks good.
I watched your video. And I think you can save yourself some significant time using larger brushes in the beginning stages regarding the shape of the figure, but also to help when placing down the mid tones, overlapping and rendering.
One of the things I learned about figure drawing using non-linear, (not line drawing style) techniques was that going from inside the figure, to outside the figure (negative space) in whole stages let me see the figure faster and more accurately the more I practiced.
It looks like you enjoy this style from start to finish so I hope that this idea helps.
This is a 15 minute study using that technique from school a looooooong time ago using nupastels to try and illustrate what I'm talking about. We had to do what felt like hundreds of these. Start with the figure shape, do the outside contour, rub it to find a mid tone, then do the highlights cause your midtone is already there, , and outside contour again.
You will subtlety find yourself more controlling where you want hard and soft edges faster.
But overall I'd say great color control. You might find yourself a rough brush that you like too to add some variety to your mark making and get away from the round edges left by the basic brush.
