Columbine Backlit

Nice sharpeness and depth of field. I would have preferred more light in the center details of the flower.

Nice shot, perhaps a little too "centered". Check out my stuff, please!

I would have stopped the lens down as far as possible to try to get the vasculature of the far petal (top left) into focus. A little bit of creative curving might bring out the shadow detail in the white petals at 12 and 3 o'clock as well.

Try some fill flash at maybe -1 exposure value to open up the shadows a little or use a reflector.
