2 minutes drawing

Great capturing, may be if you show the hips more like a block or like pants it would indicate even better the way legs come out and which side of the pelvis is facing.

Let's put it that way: you are in the process of eating your spinach, which is great. It doesn't look super aesthetique, but it isn't supposed to. Your line quality and the way you analyse poses look very disciplined. You will get a lot of pay-off, when you go back to regular drawing with the additional practice in observing the masses.

For what you are doing now, it could be even better to draw the hip either as a box or as undies,.... that way you give it also a clear orientation in 3-d space, which can get a bit lost with basically variations of spheres for the hip. That's not a "You are doing it wrong" comment, that is more a "You could add one more weight to your reps that way", so its up to you.

Well done. I think you should include feet as simple lines!

good job on these! i can see clearly the poses, but proportions are a bit off, in some legs are very small compared to torso, I think you can start adding hands and feet to your studies too.
another suggestion is to draw one figure per page it makes it easier to read the poses and and to get the proportions/pose down.

keep up the good work
