I think the comments you received during the challenge sum up the strong points about your entry pretty well, dynamic lines, sharp, vivid color. Looking at the top ten scores from this challenge, six were close-ups/macros (Abstracts) and the other four were landscapes. Your image falls somewhere in between these two categories. Your image fits the challenge well but the subject you chose was a little busy, with lines going everywhere, shady and sunny areas, and what ever that is in the bottom left corner. The only suggestion I might have to improve your score would be to zoom in on one the elemental groups in your image to simplify the composition. My choice would have been the tightly grouped bunch of reeds in the upper right corner, the ones that have the strong sun light. I think this image is done about a well technically as you could have done and I look forward to seeing more of your work in future challenges.
hmmm, hmmmm... this is a rather confusing image, with the background still in such sharp focus. i find my self trying to decide which one the subject really is. wait a tic...it works! i really enjoy this shot, the colour is very vivid and pleasing. well done.
