Eh, they look somewhat similar, except Sheik doesn't have that one bang hanging over his left eye >.> Also, Sheik is a girl in disguise while Deidara’s appearance just makes people think he’s a girl :awkward: Lastly, Sheik has red eyes while Deidara has blue…….and Sheik’s ponytail is tied up to be straight while Deidara’s is just a half pony tail. So……I guess they’re noticeably different actually :S
