Seems to me you've used a filter on the top half, clever if you did. It pushes the foreground nicely although the light drops off right up front a bit. Nice tone throughout with wonderful colour. 7
I love how the light focuses on the flowers. Did you do that through post-processing or did you find the scene like that? Either way, it reminds me of the style of painting popular in France in the early 1900s.
this is definitely my biggest favorite. Even though it breaks the obvious rules of composition, the bright red flowers lead the eyes to the bright sunset. Just enough details to keep from distracting.
Beautiful movement, on top of everything else. As an aside, it responds the best to the challenge: flowers in garden & field. I can almost hear the soft cries of cicadas. First page stuff.
