hi, im going to start on what you need to focuse on because i looks like you arent confident in the lines you make i would recommend doing some studys of the "line of action" which is the general line or movement of the person you are drawing focuse on how the spine curves with one line and do a few practices with only focusing on that then when you can identify it almost immediately then you can work on adding the head ribs and hips with simple lines or circles and what can help you under stand the pose more is if you put a cross where the body part is facing then you can start adding the joints and conecting them with a line
