the brown in this picture does not work for me. The focus of the image would stand out more if the POV was from a little more to the left. This would move the focused stamen (?) in front of the background making it stand out more. Changing the POV would also get the other stamens (?) a little more out of focus. Its interesting (kind of) but doesn't really hold my attention.
To me, this is a visually pleasing image, but the center composition and the lack of interesting things in the subject makes it appeal a little less to me. Maybe including more of the flower and add some more depth would do. Anyhow, I like it.
