This is great for a ten minute drawing.
I was impressed by the work of Salt Simulacrum; I want to imitate his gesture drawings and you might find them inspiring. He simplifies the skeleton and uses a lot of flow in his gestures. I have always found following the practice of accomplished draughtsmen a good way to learn.
I intend to set myself a goal of 10 hours of gestures a week; this way, in three months I hope I will see progress.
Great drawing Ashton!
You really captured the weight and tension; I love that the internal structures are visible.
