Hello Retrocrisp.
my advice to you is, to dont stop practicing the figure drawing, do it maybe 1 hour a day or a few minutes before start drawing your doodles. It can help you to relax your thoughts and hands to doing something that you like :).
other advice is to start learning about the human anatomy, it can help you to understand every point of muscle and joint.
Some books to understand anatomy are
Andrew Loomis head and hands
Andrew Loomis Figure in action.
Some atlas of human anatomy.
