Haunted by the promise

Each year the lilies come out at the local park and each year I try to capture some essence of them. This is a block in my photography that I must overcome. What is it that stops me from focussing my efforts to get the image I want? I think part of the problem is they remind me of images from the past in both style and content, but my processes are at odds with that thinking. An itch never scratched.
