Great work, I applaud you for hitting your goal!!! I love how freely your lines move. The proportions are good and the feet are staying beliavably on the ground. As the next step I would suggest you do longer poses, focusing on where the light and shadow hits - you can use the beautiful line variation you already have in your pencil in a more effective way by doing a thicker line where there's shadow and a thinner one where the light hits. You could also start shading in the different shapes of the body. Try squinting with your eyes to make out the darkest vs lightest places! Good luck!!
