Nice leaning pose. I love how great a job you've done with the way you kissed the paper with your crayon, or something. (is it?)
What I really need to see from you, is more looser, lighter, longer, larger, and livelier lines of action and rhythm. Why don't you please do this interactive drawing tutorial here: https://line-of-action.com/learn-to-draw The basis is as a result, you'd start out with the 30 second quick warm-ups, then you'd get to the 15, 10, and 5 second scribbles. If it's just a bunch of scrawls, that's normal, because, it teaches you how not to be too precious with your sketches. Not to mention being a bit more vulnerable with yourself and your stuff.
If your next goal is to make use of drawing light lines, then make that your custom goal on your studio page. So cheers to you, and all that sort of stuff.
Thank you! I really appreciat your comments and advices.
