I think it is nice execution , with the silhouette too because it is simplified in favor of movement. I would say to keep the silhouette out if you are really new. It is better to be focused in the gesture than the mass that describes that gesture. I mean, you see it. But you need to focus on flow of the pose and try to get it with just descriptive-simple line/s of action. Mass and silhouette if for later in the process. Nice result anyway, keep it up!
