hey Willy, well done with these sketches. They look great. I like to have the gestures of a limb going in the same direction. For instance the leg’s gesture usually flows with the quad which counters the hamstrings gesture. So i usually pick 1 or the other rather than having the gesture of the quad and hamstring at the same time. The arm is similar. It’s mainly because the joint (knee and elbow) bend in 1 direction so if you illustrate the gesture from shoulder to hand it influences the smaller gestures. If that makes sense. hope this helps

Nah, you're not just scribbling, these look good. Just make sure you're doing long poses and getting into the nitty gritty of things. When you understand something deeply, you learn what's essential. As long as you're doing that deep work and not just gestures, you'll be fine
