im not pro my self but try to focus on different form for different part in the body, robo-bin can help you to get the perspective and the proportion right

Definitely a really great start on gesture! Well done!! :D When gesture drawing, the golden rule is express the pose in the simplest and quickest possible way, while still making sure that the gesture is readable; i.e., that we can look at it and understand what the model is doing. I'm definitely seeing a lot of that in your gestures, so -- awesome!! That's the toughest aspect of gesture drawing, and I think you're getting the hang of that pretty well. :) I'm impressed! To answer your question, here are maybe some thoughts to consider, as to the purpose of each type of gesture drawing: In 30 second poses, the ONLY thing that matters is to convey the basic, essential information about the pose. What's the torso doing? What are the arms and legs doing? If doesn't matter if you're not drawing the full leg or both sides of the arm; it only matters that we understand what the limb is doing, in which direction it's moving, etc.. In 2 minute poses, you convey the essential information about the pose, and then you add in a few more strokes as mental notes. The extra strokes aren't meant to be details or contours; they're supposed to be notes to self that you'd want to keep in mind if you were planning to come back to this figure and flesh it out into a full drawing later. Things like: I want to make sure I capture the tilt of this shoulder, the angle of the elbow, is this foot completely sideways or is it actually moving "towards us" a little? Which is the side of the hip that's carrying the most weight? And so on. In 5 minute poses, you have the most time and freedom, so on top of the basic information about the pose, and those little mental notes, you can also allow yourself to hint at some of the underlying anatomy. For instance, you can place little marks to indicate the basic outline of the clavicles, the biceps, the bony indentations of the hips, etc. Anyways, a bit of a long digression, but that's basically what I'd focus on when gesture drawing, so I hope that answers your question as to not being 100% sure what you're supposed to be doing. :) Also, as another note, maybe I'd suggest posting your drawings directly into the comment box, instead of linking to an external service like google drive, just because humans are lazy and most people won't click on a link just to see someone's drawings, haha xD If you want eyeballs on your work, make it as easy as possible for people to see it! :3 Still, as I said, great job!! Keep on grindin' the grind, you're definitely on the right track here! :D

Wow, these are awesome! They communicate 3d form but feel very organic at the same time!

So pretty! These are really effective; great job!! :D

Oooooo very lovely!! I know you posted these a while ago, but I just wanted to say you've done a great job at placing all of these blocks and cylinders in perspective; your work really inspires me to keep working on the structural soundness of my own mannequins!
