I’ve been doing those 1 minute sketches so i could capture the pose and i understood that there’s a specific flow of the body. Though i find some of them seem less dynamic and have been questioning on how do i improve it, is it a matter of experience or there’s a specific trick for it? Also, if my rough sketches like these are good enough, is it time for me to start learning line art quality or similar things? My goal is to be able to draw characters in fandoms which, from what i understand, requires knowledge on correctly depicting the body, clothes, faces and hair. Please help!

I've started learning proportions for a while now and I'm uncertain whether I should continue proportions of move on to something else. I got recommended to start perspective or head/face but i can't decide what to do. I've learned how to draw mostly through youtube, specifically Draw like a sir and Proko. Please help!

PS: I couldn't find the reference images since it was some time ago.
