Okay.
Let me start by saying that anatomy isn't my strong suit, especially male anatomy. BUT! The thing that will really help this drawing is a pose that is both more natural and more dynamic.
In this case, you've got a guy in a pretty neutral stance, with his shoulders and head more or less straight, but one arm stuck straight up in the air. This kinda works for the keener in the classroom begging for teacher to call on him, but it doesn't really work for a Jedi knight who is channeling the FORCE into his hand.
smile So I tried to find a pose that showed how much effort was going into the hand. Sorry about his right arm, I know it's a little screwy. I was unsure of what to do with it since he had the lightsaber in turned-on-glowy mode... I also made one of his legs a lil longer than the other ^^; but mostly I just wanted you to get a pose idea.

I hope this helps!
