I like this image. There is a surprising amount of rich detail in the road surface. I would love to see both pairs of shoes included in the composition.
This is a good image. I think the elements would be stronger if it were possible to create more symmetry between both sides of the image. Also, I might consider shifting the exposure up a bit to include a third of bright, overexposed sky into the composition.
Some really neat elements in this photograph. I like the contrasting light and color and the diagonal lines of the grass. Don't be afraid to "harvest" elements like the two small strands of grass that are out of line with the rest. Also, it might be nice to shift the stalk with seed pods into the left third of the frame.
