These are lovely! This is very effective practice with the loose inclusion of shadow mapping. Your next step might be anatomy practice. I am looking at particularly your ankles. The proportions are nice but you don’t want loose work to become lazy. I recemend a book morpho anatomy for artists about 22$ or you can go on the you tube channel “the drawing database” for a college level course for free. I am currently doing it myself.
I am not sure what you are asking but I will try. Gesture drawing is loose, it's about the movement or basic form of the figure. It helps to practice body proportions until you just have it down by memory. You can either use just lines, do contour drawings or use the side of the pencil or charcoal to add value. I don't have a full membership so I can't post anything but you can find great tutorials on youtube and great examples on the net.
I am not entirely sure what it is that you want, but I will do my best to respond. The line work in a gesture drawing is very loose, and the focus is on the movement or fundamental form of the figure. It is beneficial to practice changing your body proportions until you can do so by memory alone. To add value, you could just use lines, you could perform contour drawings, or you could use the side of the pencil or some charcoal. Since I do not have a full membership, I am unable to submit anything; but, if you search the internet and look on YouTube, you will find many helpful tutorials and examples. basketball stars
