Beautiful colors going on here. The lighting you captures is surperb. I love the lines you created with the grass it moves your eye throughout the frame but leads you to the upper right which circles distract a bit. Though I think that has more to do with the actual lens in this case, because I think the use of depth you were use was a good idea. Focus is great. A really nice capture.
I agree about the circles. But it is a very small thing for me. The way it is, I still LOVE the image. Especially the colors; autumn is my favorite season and the colors here really bring it to life for me (even if those don't grow in autumn, the colors are just perfect!).
I just have one suggestion: I think you want the eye to focus on the stuff in the lower part of the image, from the diagonal down. The blurred circles in the upper part distract me somewhat, so I'd suggest just blurring them out. With that, I think this would make a great print.
