Outstanding! The color is so vibrant in this image. Very clearly meets the challenge. The shadow behind the leaf is perfect.
What could be better with this image? The hair/crack/whatever just above and to the left of the leaf is distracting. The rest of the "schmutz" in the cracks is OK, but I think the picture would be a little better without it. I would love to know if you just happend upon this or set it up.
Excellent job! A very strong 9.
The high contrast yellow plus the rule of thirds and the bluish stonework really make this photograph appealing to me. To add the rule of thirds really makes this photograph work.
