Very interesting study, but not what the challenge required. Also read the tutorials and search the forums to learn how to enter pics with the best file sizes (i.e. the bigger the better... use as much of the 150mb as possible and have your longest side set at 640 pixels). Godd luck in the future. You have a good eye.
Smaller image. Might be a nice image for something else. I don't notice a woodie here, and that was kind of the purpose of the challenge. The colours of the flours look over saturated to me. Although I like the roots behind the the colour in front, it still feels oversaturated.
Nice flowers and contrast to background, but where's woody? Also, please make your images larger, see the tutorial on preparing photos for DPC challenges.
