Excellent. I want to read your comments after the challenge to see how you shot this.
i placed myself around a corner near where the cars stop, and took pictures of people
that look in their thoughts through their windows ... this woman was in a cab, ... hence the reflections and the colors that i thought was perfect for the mood ....
This is an idea I like, although i think the execution really has problems - it looks straight-from-camera, and lacks a great deal of definition, and certainly of contrast, and is dark. I'd brighten it, raise the black level to return the shadows, and certainly convert it to black and white - what colour information there is here, is badly off and very green. In bringing that definition to her face, you'd probably find some of the highlights in the reflections would burn out, but as the real point of this image is that face, that wouldn't be an issue really - it would add to the 'street' sense of the image.
I really love this image. The color adjustment makes it look very somber. Very good detail on the reflection, which works well in the idea of reflecting on yesterday. The more I look the better I like.
