A spent sunflower tiredly leaning--nice subject for duotones. I love the texture and the way the lighting shows it off!
Composition: The eye is led in from the left by the stem and comes to a stop at the seed head. There is, after that, little for the eye to do except start over. The balance within the frame feels awkward--though that may help convey the inevitable falling of the flower stalk. Perhaps other approaches to the framing or cropping would have worked better--hard to say.
Technical: I see nothing wrong with this technically. There is a nice range of tones, detail in the shadows, and various tones in the sky which help avoid a dull backdrop to your subject.
Overall, I think you have chosen and interesting subject, tried to convey a mood and suggest a story. It's not the sort of image that will immediately graab all viewers--but if one is willing to spend some time with it, they will discover its subtle appeal.
well done.... I kinda relate to this shot as I am feeling kinda bent myself after voting on so many images.. and hitting the refresh button.. that bumps up my score to an 8 on this one :)
