I like the idea and composition. I think that the overall image is too bright, though. IMO, a darker image with bright highlights increases the feeling of "dawn" and is more dramatic.
could be crisper. on a totally untechnical side of things, how does this fit the challenge? are you trying to make chess cliche? title doesnt really fit inmy opinion apart formt he yellow light./...
Nice lighting and angle... I think I would have liked to have seen it a tad sharper though, although its really not bad as it is now... Good luck with the next challenge!
I think focusing on a more middle subject in the line vs the front subject would look better...also I wont what it would look like with a diffrent white balance
