Gestures and Longer Poses

It looks like you need a bit more of practice - overall it looks superficially good but the poses are too stiff and superficial. Maybe try warming up more and letting your mind wander while drawing, to make looser lines that glide freely on the paper?

Glad to hear you got some encouragment and inspiration! One thing you might want to keep an eye on moving foreward is your proportions. Particularly for your second gesture, where the torso looks pretty long compared with the rest of the body. That being said, I think your third gesture has a good sense of volume and looks pretty good!

Keep it up :)

『Left drawing』

How about making the shapes of the chest and pelvis a little more realistic?

『Central drawing』

Pay attention to the ratio of the legs.

It may be a little too short for a real person.
(That's cute in the manga character illustrations.

『Right drawing』

””sitting quietly””
I understand this behavior well and it will be helpful for me!
