I am impressed with your dedication to improving your anatomy drawing skills. It takes a lot of practice and hard work to become skilled in any area, and you are making progress by actively working on your weaknesses. Don't worry about whether others perceive your progress the same way you do, as long as you are continually striving to improve, that is what truly matters. Keep pushing yourself and trying new techniques, and you will see the fruits of your labor. Your determination is admirable, and I wish you continued success on your artistic journey.
Best of luck and keep up the great work!
