Personally i think you should try to make another one... I don't really like the sig size either

I would go for the Shadow one. Even though i'm not a fan of pixel stretches it's got a more textured feel and unifed however your Naurto is very plain, the render is poor quliaty and i don't really like the scanlines.
Just tone down the brightness in your shadow sig with the burn tool , set to a soft brush
