It would be greatly unfair to just make a character set offlimits. The Nara are powerful, but not completely imbalanced. All it would take, in theory, is a very powerful genjutsu Kai to break a hold, but that would only work once. I'll allow the character on the removal of Self-Restraint and the inhibitors of Katon being highly-chakra consuming and his sensing being limited to his concentration.Shadow Sewing is another issue. The area in which Shadow Sewing is effective is stationary. I know some people try to relocate it. That's not how it will work. Once the tendrils are summoned, the entire jutsu must be reused to displace the tendrils. Basically, you can't just chase people around.

I'm not really getting what you mean with Shadow Sewing. Isn't the historical limitation on the technique being the total volume of the shadow? So you could create a bunch of tendrils, but they wouldn't have as much range as a singular one? If you can't do any adaptation to the movement of them, then the technique seems kind of useless.
