As much as I want to be drawing portraits, I also want to drawing quite a lot of poses. I love drawing poses, because it catches dynamics, and pay attention to less detail by going for the right move. It pays attention to motions and every of its derivatives.
That's why I used lines and circles for guide. Circles is for the joint; every break I made, and the lines are for the dynamics. Though I've not perfected this steps, I know with time I will totally get it right.
HAVE FUN GOING THROUGH THEM
