Hey Shane I think have some advise that may help. Looking at your drawings there is some nice stuff. You are simplifying and not focusing on the contours that much. Motion comes from the relationship of one part of the body to the next. For example in the attached photo you can see that the head sits farther to the left of the pelvis, even going a little past the left shoulder. In your drawing it is having a latter effect where all the parts of the body are fairly straight up and down with one another. If you have those photos available to breakdown I would recommend you put them in your software of choice, or print them out, and drawing straight lines from different parts of the body to see where they hit other body parts, or don't hit. I would also recommend that you start paying attention to the pelvis and the direction it is going. Many dynamic drawings have the shoulders going one way and the hips going another. You can see in the breakdown of the photo that her let shoulder is going and her right is going up, which you did capture (I would push the angle of the a little farther to really sell the that action). Now with the pelvis, I am not getting that it is facing a completely different direction than the shoulders in your drawing. I see you tried to indicate it with the contour lines, but I would do what you did for the shoulders to the hips as well. It will better sell the twist. I know I threw a lot at you, but these are looking promising. The last thing I would recommend if you can afford it is to check out Drawn to Life by Walt Stanchfield. It is like the bible of gesture drawing. I hope this helped, good luck!
