Looking for feedback

Hi! Below are some my latest gestures. First four are 3 minutes and the last one is 10 minutes long. Would appreciate any feedback.

P.S. Also, could anyone explain what's the difference between gesture drawing and figure drawing? How I understand it is gesture drawings are fast and rough (<10 minutes) whereas figure drawings are their more detailed and rendered versions (>10 minutes).

My feedback, don't take it as gospel. I think you are currently focused on identifying individual lines on the reference, but don't do literal construction a lot. That isn't wrong, it makes a lot of fun and all, but it isn't a particularly fast way to progress. The quicker way to progress is instead of trying to draw what you see on the reference, you learn how to draw a mannequin from a fixed set of primitives, simple 3-D forms. Here is a video of one set of such primitives, it's not the only possible one, just an example: &list=WL&index=99
Once you taught yourself to draw such a mannequin in a neutral pose, you stop drawing from the reference, but instead only use the reference to indicate the posture and perspective, that your mannequin should assume. (also, you possibly have to add fatty pouches for less-than-lean body types), and stik with drawing that mannequin.

Doing this, at least for me, is way less fun than actually drawing from reference. It forces me to ignore all those beautiful relationships that I can discover by admiring the reference. But what it does is building some reliable framework, so the next time I skip mannequinization and just return to drawing from reference, my lines will be a lot more convincing, relations will be more on point, I will be more aware of extreme aspects of poses.

I would advise you to do that construction/mannequinization grind at least to some extent, even if you (like me) feel like it is less fun than really drawing from the reference. It's a bit like the "eat your vegetables" part.

About the difference between gesture drawing and figure drawing.... Let me put it this way: most art teachers are renowned for being good at drawing (or painting). They are not renowned as poets or philosophers. Don't start to meditate too much about anybody's specific choice of words, because there is a good chance, they are not even aware of the specific difference you are looking for. And certainly don't expect one art teacher to consistently use the terms some other art teacher has established. If you ask an art teacher for an exact definition of what they are talking about, they will vaguely wave into a general direction, tell you, that "that" is what they clearly meant, and expect you to live with that.
If you want to learn from them, look at what they are drawing, and try to understand their words from that, not the other way round. Drawing is a manual skill, and even pushing someone into the right directions with words alone is extremely hard.

Thank you for your reply!
Yes I probably do lack a construction in my figures. I often forget this part when switching to longer timed poses (1min to 5min, etc.). Will definitely try what you suggested.
