This is a really beautiful picture. I love it. You have a really interesting/unique style. I like it a lot. I love how much action there is in this picture, as well. It's really expressive and the attention to detail in her outfit is fantastic. I have to admit, I've fallen a number of chapters behind in Bleach, but I love the she's an interesting character.
I can't really think of anything that could need some changing in this picture, though I do think there is something in the face that is in a different style than the rest of the picture.
It doesn't detract, and I can't put my finger on what exactly it is, but something is different. Love the picture, though.
