A little too small to be fully appreciated this one, but the light on the leaves is lovely. You clearly see the plentiful beauty of this time of year! If you could get closer to the trees next time that would be better, so that we can see more detail and lose the unnecessary elements such as the darker trees at the right side. Good luck.
You're allowed 640 pixels on the long side, and I suggest using all of the size allowed. This photo is too small to have much impact. At this size, there doesn't seem to be a focal point, though the colors seem nice.
you have probably heard this a few times but it may bear repeating. Make sure your submission is as big as you are allowed to go. In this case 640 px on the longest side. I'd recommend this tutorial:
