this is a good design. it should be on a shirt, put me up for a dark and white ( though would have to invert the white for a white shirt) ill buy a few and pass them along i could defiantly see one of the local teams i play with using this design on a shirt.
i dont read naruto so i'm not sure if it's a pose used in the manga. i would expect lots of manga uses action poses similar to this so i can understand if it looks like something from naruto. thanks for the comment!
