It is always encouraging to see seedling coming through. Unfortunately, they don't always make an interesting picture. This is one of the better ones, and yet,
it doesn't have much impact.
I think this is a unique idea for the challenge. It works..for me. I would just suggest that you add some saturation and contrast. It's pretty washed out here and there.
Nice use of color and an original take on the challenge topic. Wish it had a bit more depth of field (or, at least had the focus point moved more towards the center) and that the weed in the lower left were cropped out.
