I almost hate to suggest it, but have you considered a soft-focus effect? If your intent is to emphasize the whole over the detail, it might encourage the viewer to step back and look at the color and shape a little more.
I personally think soft fall colors and soft focus go well together, but it may be a bit schmaltzy for your tastes.
Given the low resolution of the jpeg, I could be completely missing the delight in the details, but I thought I would throw it out there.
