Good line of action . Try drawing with your shoulder ( https://www.proko.com/course-lesson/how-to-hold-and-control-your-pencil/discussions) to improve line quality. 2nd and 3rd poses seem off balance. Not to worry for now. There is a lesson by proko when you go further ( https://www.proko.com/course-lesson/how-to-draw-balanced-poses/discussions ) Keep up the good work !!
