You based it off the anime WAY too much...
But I still like it.
And to deathclaws, Sasuke is vulnerable when he does the chidori. He has to engrave it right into the opponents body in a one-arm-in-one-direction-only-
focus-on-whats-ahead-of-you way. Rock Lee, if he had seen the move before, could've circled fast around Sasuke's position, slide under the chidori, or attack from above; Sasuke can't defend any of these areas in his chidori arm-out position.
Rock Lee also doesn't have to hold his arm back. That gives Rock Lee a split-second advantage.
But this is a cartoon, not some sci-fi thing. Awesome fights!
