Greetings from the Critique Club, and welcome to DPC!
I love the creativity in this shot. Definitely outside of the norm for this challenge. That's not always a good thing on DPC though. I think the biggest issue is that the subject is obviously not a tree. When I voted on the challenge, I thought it was spray painted popcorn or something. Also, the shininess is distracting.
I do like the overall composition of the shot. A single tree on the right, a curved horizon, and a beautiful blue sky complimenting the yellow in the ground.
The lighting on the ground is good. I think the lighting is too strong on the tree though. Either less lighting, or a less reflective coating may have helped. I do agree with the commenter below that the overall feel of the shot is a little dark. Would have liked to see the sky glow a little brighter. (Tip: Bright colors work well on DPC)
Focus is good. Gives the photo a very 3 dimensional feel.
Props for thinking outside of the box, and taking so much time to set this up. I think in this challenge, though, there were a lot of breathtaking landscape shots that captured the higher votes.
