Hi Laitochris,
It is my first time critiquing, and I hope that I won't offend you.
Nice work on your figure drawings and good first step on drawing figures! I do like your proportions on the body.
It is just me assuming, but I see that you make the blocks of the body (head, torso, hips) first and then add the legs and arms?
I did look at your 30 second figures and maybe a small suggestion is that try to draw the figures first by starting with an action line.
By drawing an action line, you get get the "flow" of the body and the base of the action that the body is doing.
Here is the link to what an action line is : https://line-of-action.com/article/gesture-basics-1-line-of-action/
I use this technique as well, and drawing an action line for the shoulders helped me tremendously when drawing figures too.
Don't focus on trying to draw each essential part of the body, but rather on what the person in the photo is doing and express it more naturally.
I hope this helps, and keep drawing!
