Critique on my progression

I'm on Ch. 2 on Mike Mattesi's FORCE. Been adding form to my figures and doing a "Blind Force" drawings.

These are my recent drawings. But, my gallery is also opened to critique. Here is also a link to a discussion that had not gotten feedback yet.

Any concepts and ideas that I am misunderstanding? All feedback is welcomed.
