The gesture on the red underdrawing without blue ink is strong and highly descriptive as a drawing in its own right. From what i can see this is true of the drawing on the far left as well, it's hard to tell with the others. I would say that when switching to the blue ink, which might for you represent some sort of finality/fatality of the drawing, the studies stiffen up because the lines become shorter, overlapping, and somewhat uncertain. This tightens up the drawings. Maybe ink is a problem here because it is immovable, or maybe it's working in two layers - which might convince you to worry more over the second.
Also, you can maybe think of it like this - quick, energetic things are light; birds have hollow bones so that they can fly and fly quickly. More lines add visual weight, this is both an observation on value and optical density. Specifically, I am talking about the contour of the hand, not the hatching for value. It might help to seperate your practice into smaller parts; try doing some sessions where you focus specifically in drawing the outline of the hand quickly and confidently (if the proportions distort a bit it is okay,), then try doing other sessions where you focus on building values on the hand.
Thank you so much for taking the time to really look at my drawing and give insightful feedback. I really like your bird analogy. I'll be mulling on that for a while. You're spot on about the blue tightening up and losing the life that the red drawing had. I'll focus on that more. I think a lot comes down to mindset and apparently when I think on form and light I stiffen up a lot. Ink definitely isn't forgiving when you put down a bad or heavy mark. And I appreciate the advice for seperate practice with specific focus areas. Cheers!

Good work!
