Very striking colors, clarity and sharpness. This meets the challenge very well especially how the sky dominates the composition. The couple in the background completes the image. However, I think the couple could have been better captured. Their legs and arms are hard to discern from this distance. If this was a sunset shot with the foreground field in shadow and the couples as silhouettes it would have been really difficult to see that they were people. Perhaps a slower shutter with a shutter burst would have produced a more appealing position of the couple?
Other than that this is perfect. The cloud cover is nice as is the POV.
Perfect composition and great colors. The choice of a red jacket is well done too and a nice eye-catcher. A very impressive shot, thanks for sharing and good luck for the challenge!
