Hey there!
First thing, the last line. "My hand doesnt get the memo" that is just lack of training, is does not mean youre training to little, it just means you should relax, keep the training and in time the hand will get the memo, constancy will give you confidence that will give you the memo. So dont worry about that part.
You didnt put any notes, but i'm guessing this are 30sec~2mins drawings.
In figure drawing that are two types of training. the Accuracy one, where you do longer drawing, trying to capture the exactly picture of the pose. That one is a more advanced training, dont worry about now.
The other training, and truly the most important now for you, is the Gesture one, where you do short drawings trying to capture the essence of the pose. The gesture of a drawing is some thing hard to explain, so go watch a vid about in youtube that will give much more precise info than me writing here, some artist pro at this are Proko (Stan Prokopenko), Jeff Watt, Sinix and many more if you do your homework.
Basicly, gesture is trying to capture the motion, the rythim, the flow of the form without drawing the simple contour.
Trying grasping the skill of gesture, youre drawing will grow better exponential, garantee.
Well, thats what i think. Dont stop drawing no matter what. Good luck, good journey.
Cheers
