Hello again! Say, Polyvios, I wanted to thank you for your feedback. I tried going for a couple two minute sketches as you suggested. It was very useful!!
I decided not to focus on anatomy so much, and drew more losely. I Drew more bold shapes and also switched to a softer brush. This is the result:

Although it is the first time trying this new method, I think my lines have become more fluid and the poses are much less static. Still have a long way to go, but this helped me get over my frustration.
I'm so very grateful for your advice. Definitely incorporating this into my routine.
Have a nice day.
