This is such a beautiful photo! I love the bright, vibrant colors of the leaves that demand your attention right away. The yellows stand out very nicely against the greens in the background, and the orange areas of the background add to the photo as well.
I also really like how you managed to get a shallow DOF from this distance, and the focus is sharp and crisp; allowing us to see all of the smallest details. Beautiful work, there!
I think the composition is wonderful as it is, but if you wanted to you could've shifted to the right (or crop) a little as there's a bit of empty space on the left whereas the rest of the photo seems to be filled with the leaves. I like the slight horizontal tilt of the trees in the background, though.
Excellent photo, I can't wait to see what else you photograph!
