These are good studies and it will take a lot of time drawing these types of studies to get skilled up to a high level. It takes some patience and grit to keep it up. You are on your way there for sure just keep doing these. It will help your line qaulity to develope faster and you will draw better figures in the long poses for example. When I was in art school starting out I would juggle gesture drawing with 3 hour figure drawing. It was so helpful to study those together. I think it is a good idea to move into other figure drawing areas of study while keeping up with regular gesture work too. All these areas of figure study compliment and inhances our learning the figure. I think you are asking great questions in your notes. Here attached I noted the need to use a single flowing S curve vs the 3 C curves to make the gesture flow better. Hope that helps! You are doing great and need to keep drawing gestures on the side while studying other figure courses as well. It's a juggling game and focus will change from one course to the other a little bit but it will all come together in developing your hand, eye and overall drawing knowlege.
