Ah... nice but not quite perfect. I sense what you see here, but things are not lined up correctly and I am not talking about the ducks ;)
Ok, why did you get low scores, it might be because the ducks are not passing in order? the dirt in the water? the view a bit far?
all above?
Ok, technically not bad. Nicely exposed sharp photo. Focus seems like where it should be. But the composition here little off, I think you could go down a little more, give yourself a little tight angle and shoot bit more zoomed in, or cropped to give dramatic lights a bit more pop.
Oh well, try more options next time, and you should take more photos of this scene... very nice place :)
Checked your page and "Waiting for the chaos to begin..." is a very nice shot. I love it.
My friend, you do have future. Keep on clicking ;)
The mood is of a sunset...though the sun seems to be still very high!
Nice subtlety of the light. I would consider to clone out some black dots and lines near the ducks. Good image globally.
