I really like your post-editing here... But I might suggest trying to get a little more of an interesting composition going here. But the color tones are beautiful. I like it!
Feels slightly off balance to me. It's the overall composition that feels off. The focal point appears to be the browning, curled leaf and the lighter area of the image near the top center. The focal point is high and centered.
Negative space is good, but seems to take more room than needed. The horizontal line formed by the leaves works well but nearly bisects the image into two parts.
I really want to see the top of that brown leaf! :) I almost feel like you could have backed off a little and maybe taken a bit off the right.
The colors, tone, texture, and DOF are all very nice here. The border is semi-transparent and is a minor distraction for the detail oriented. :P
