Colorful Fall Leaves

I took this shot vertically toward the ground. Decent shot of fall

leaves or is it too two demensional and/or too cluttered?

I think the way you've cropped it is fine. Exposure looks OK. I would have prefered punchier colors to really make the red stand out, but perhaps it is a problem with the printing and/or scan. Since it was taken is shade, you could try a warming filter (81A or 81B) to enhance the reds.

The arrangement looks contrived. Red leaves surrounded by all those brown ones? Two green ones nicely centered on the red leaves? A bit too much of a coincidence for me.
