Great perspcecitve and colors. It appears to be leaning a touch to the left. Maybe a little tighter cropping on the sides to decrease some of the negative space, and more of the stem included to show more of the plant.
Interesting. Was this the actual color of the flower? The bottom yellows are a little too light and bright. I think i would have tried a different crop or perhaps a different angle on this. It's good, but something is missing. Good color and contrast on the sky.
This is my favorite photo in the challenge!! You have beautifully captured the flower and it is nicely contrasted against the blue sky with the wonderful fluffy clouds. I love the perspective, the composition, the color -- everything!!!!!
