edit: I painted over the sketch bahahaha
I like his diamond tattoo~!! too bad it's usually covered up XD
omg for the longest time I've been confused by ghirahim's left ear supposedly looking human! *__*
But actually it's just in the model in-game where it's like that.
In hyrule historia, his art shows two pointy ears! ` 7 ` <33 [link]
Ghirahim is from Skyward Sword
