I don't want to say anything mean, because I know this is the rough draft, so I'm sure it'll only improve. Mangas are not easy at all. So I think you should work on how someone is wielding a weapon, because I can't see Sasuke's hand gripping the sword really. I'm not so good at drawing weapons but in mangas and animes drawing the weapon right is a key part of an action scene.
So, when drawing a weapon try using a ruler to make it look straight. You should also try using weaponry effects to give the character motion such as adding sweeping curves or wind around the weapon. That's what I've learned, but I haven't really used the advice.

By the way I really like how the Sakura came out in this drawing, I can't wait to see the end result to this. ^^

cool^^
