Did you shoot in monochrome, or did you jsut convert? Seems to me that all images record in colour, then the camera can be set to ignore the color information, or you can convert it to b&w later.

This image works well for me. I think you have captured it well; maybe a bit more contrast would help, but then again, the subject is a "soft" subject, so overall one may even want to have it appear soft i the finish as well.

Only thing that bugs me about this image is the branch in the foreground ...
