first congratulations for your great effort and perseverance.
I do not have much to be drawing but I already passed where you are, this drawing is very fruitful and more if you do not see your progress, but it is part of the experience.
-The first thing is the anatomical study, draw the whole body in three views, front, profile, 3/4. This helps to memorize the basic canon of the body, then you can study the body more thoroughly.
-do not compare your work with that of other people, not all of us manage to advance at the same pace.
-Finally, do your sessions in class mode, working with different times works very well.
keep negotiating and studying, find a balance between practice and study and I assure you that you will notice your progress
