This is quite excellent. I can tell you worked hard on this.
I absolutely adore this version of Chibiusa. Usually she is my least favorite character. This armor version of a costume though, her feisty look, her thick eyebrows, the whole color scheme of the picture, and she's wielding a sword (though a slighty disproportioned one, as I am sure it is rather unbalanced) - how awesome is that?
your heart motif is lovely i mean, its over rated in most art work and for chibiusa in general but it is fabulous
