I agree with Walter and Neal: this has a good sense of mystery about it - like you're climbing out of some deep, dark hole... You might try lightening it a little to bring out some of the detail in all those great roots and vines!
This is my favorite kind of picture. Dark, moody, maybe a little spooky. The light spot gives it a great sense of depth. As I see it on my monitor there is no detail at all in the foreground. There is probably interesting stuff there, but that would have been a different picture. This is nice.
