I THINK this drawing was inspired by a fanfic I was reading at the time. It was a Shugo Chara x Kingdom Hearts crossover where Amu was in the world of Kingdom Hearts. I based her hat on one I had at the time and this kind of what i pictured when I read this story. She was called Brave Heart, kind of like an evolution of Amulet Heart I guess with keyblades. Yeah I don't know. But hey, it's colorful.
