Hey mil3s, Your drawing looks really nice, you have gotten pretty good at these kinds of drawings. I think now it is time to start to refine some of the more detailed areas of your drawing. I think what you need to focus on more is your edges. You tend to make all your edges pretty hard, especially when transitioning from shadow to light. For our drawings to look convincing, we must have both hard and soft edges. A basic rule is that cast shadows have hard edges and form shadows have soft edges. Also, make sure you use your cast shadows to reveal the shape of the forms that it is traveling over. It is another tool to help give our drawings dimension. I did a quick sketch to show you what I mean, I hope it helps :)
