10 minute sketch.
I think overall, your drawing looks great, the proportion is on point, love the fingers, I also love the dynamic! on the other hand, the lines look rough, and the shadows are too dark.. But you can work on that later. Start from practicing to make the lines first. You got this!
good luck :D
Better. The right-hand looks good. The overall figure is good, Is the drawing an ink drawing. I like pen & ink drawings. Continue work on hands and feet. You are making definite progress.
