Typically I'm used to seeing a sunny looking sunflower in direct sunlight with blue skies and a few fluffy clouds in the sky. This a is an excellent juxtaposition and contrast. The sunflower looks like it's about to be blasted to bits by a major thunderstorm.

P.S. Have you ever thought of writing a narrative to accompany your photo?
A different sunflower photo. Not a sunny day, but cloudy and possibily will rain. Hence the face of the flower is dark. Seems like waiting a sunny day.
I like the angle and composition of your photo, Snez. Not the typical presentation you usually see sunflowers. A nice dramatic sky in the background. Good job and thanks for sharing.
