This piece is magnificant. Perhaps enhance the walkway a tiny bit more. The light is over powering it just a bit to much. Also try deeping the green, and making the browns more rich. In other words have the "earth" colours show more. I get the piece is about the light, but take it back a tiny bit. You could also try adding some shadow play behind the light, like a human or death figure. I still give everything a 5 star because of the feelings I had with this (wonder, sadness) But like I've said, its magnificant. Seriously breath taking.
The image angel, positioning of the camera and location are all beautiful, but like lower comments from others go, I have to agree with a little more enhancement to finish this image off to its full glory.
More visibility of the green, maybe a little more Contrast and tone down on the brightness coming through, or making it more defined, like a beam. But I also like the coldness of it, giving it a sense of unknown.
All in all, I love it and can see why you chose it, it could be said to be a path to a wonderland through a forest.
