Hey there! So I'd highly recommend that you study figure drawing and anatomy. Do not start studying the muscles, but first study the proportions, drawing the figure with simple shapes, and then study a bit of the muscles so you can understand their forms or volumes. Notice that in you drawring, there's no clear indication of the muscles because of the lack of knowledge. So, spend some time learning the fundamentals and then you'll see that you'll improve your drawing! :D Keep it up! | Artwod Feedback
