The avatar itself is quite neat. Her facial expression and the overall style seem run-of-the-mill, although I can't help but feel a sense of originality in that very picture. The girl itself is nice to look at as well. The only thing bothering me are those two kanji in the picture. BUt that's just me. I never liked any form of writing in avatars, stuff like that, to me, belongs in a signature.
Overall I'd call this avatar commendable and give it a solid 7.5/10.
