It all looks like good practice, and I see the action line there now. Makes it really easy to tell what's going on. Torso spehere seems a bit big but it's just a small caveat.
Doesn't seem like you are using rulers for perspective though, not sure if you chose not to use them for practice, but in case you haven't used them much, give them a shoot, they help a whole lot when it comes to perspective work.
