Damn dude, keep trucking those gesture sketches. The main thing though is to try to think of the action with those. I'd highly suggest checking out Villpu's stuff for that. He's definately a dude when it comes to the gesture. First draw out the action that your wanting things to do. (This can use a stick figure that utilizes bone structures) and followed by adding basic forms for the body structures.
Bridgman and Hogarth studies are lookin solid so far. Keep at it and I'll check in later.
