Chiaki.

I guess I can agree to my previous speakers, but what I'd like to add is that, after thinking about it, I like how the background is also very strong in colours.
All fits together in this picture, the colours, the atmosphere, everything.
She is like a part of her surroundings, as if she was some sort of ethereal nature, and very well represents autumn in its beauty.

I don't know if this is what you intended, but by not making the background less dominant you put the focus on how she belongs to that place and time of year, and not on her as a model.

And the name is absolutely fitting the whole impression this picture creates. <img src="e.deviantart.net/emoticons/s/s…" width="15" height="15" alt="" title=" (Smile)"/>
