It looks like you just need to keep going, the more you do the better you will get! The heavy outlines are not always necessary, but look better when varied - sometimes heavy other times light or even not there. It depends on what style you are wanting to develop - animation style or fine art, etc.

I think you did well! I would show a bit of overlap in the arch of the back, as the skin would fold in upon itself. Also, not sure if you meant to turn her toward the viewer but the front of torso is a bit slimmer if she is facing the same way. Also the buttocks are a bit lower and I believe would be going out a bit more. Subtle changes!

Imagine the bone with the head or ball of the femur in the hip socket and so the top of the bone that is "showing" is the great trochanter. If you stand up in that pose you will feel that there is an angle to the hips with the weight bearing hip higher up than the resting leg. So you were close on that left one, but I would raise it up a bit based on the angle of the hips - does that make sense? I'm no expert but that's my two cents lol.

This looks great! You captured the gesture and energy nicely with that left leg coming forward in space. Here are some picky suggestions that could help: You've exaggerated the pose so that's probably on purpose, but try looking at the negative shapes (the air space) between the right arm (her left) and the torso - you will see a difference, same with between the legs as well as the left arm having more of a bend. Also, the upper torso is too narrow which makes her breasts too close together. Easier said than to execute and still keep that energy!

I think it's fine to incorporate the bean - and super helpful! I recommend focusing on the gesture or rhythm first and then doing the bean to add in. You can see in the video that Stan uses the bean, especially on the compact poses. Your main goal is to capture the rhythm, the gesture and the energy of the pose first.

I would suggest "drawing through" on your neck, so basically, just draw a cylinder. You did it a couple times and that's what my instructors have always told me. It makes it more 3-D and more believable.
