Great start! You make really light and loose lines which are great for finding natural-looking curves and straights in your figures. I also like your understanding of the arms and legs, especially in the top right drawing. I think going forward you should try some longer poses (1 or 2 minutes) to add a little more structure to your abdomen and shoulder sections. Try to find some of the natural curves and contours of the body's shape like where the weight hands or where certain bones cause different lines in poses such as the one used in the top left drawing. This is an excellent start to figure drawing and congratulations on starting this new journey!
You have a really beautiful expression of movement in your work, and I specifically like the curves of the arms and legs of many of your 2 min figures. You do a great job of identifying and demonstrating where weight is carried in the figure. Spend more time working with the male form and perfecting the shapes/lines within the shoulders and chest region.
