Hi!! you should definitely be focusing more on smaller timed studies(like 30 seconds, 1 minute and 2 minutes). You'll build up your visual library and muscle memory much faster that way, and it will force you to identify basic shapes and how they divulge from contours, which will improve your flow, anatomy, and proportion. I'd also reccommend looking into Reilly rhythms. It's a system that helps you measure the body based on how parts of the body are positioned.
I'm not explaining it well, but take a look at this video and
Proko has a lot of videos on figure drawing, so I'd recommend taking a look at them(especially the one on landmarks, the ribcage, the pelvis, and the robo bean). I know it seems overwhelming but it gets easier pretty quickly, especially if you do it every day. Hope this helps!!! You're doing great!!
