Here's a shot - nothing to super duper. The image has a very deep DOF and the tones are all sort of the same, except where the light hits edges, etc. There is a LOT of green and brown, and everything sort of runs together visually. The fence in the foreground is a nice element that has an interesting texture and the tuft of grass that is camera right has a nice glow to it from the direct sunlight.
I made the foreground the focus and mocked up a lens blur to separate these foreground from the background. The hideout is still visually intact, just separated. I dodged the fence and the front of the cabin, added some local contrast and a vignette. I tried to preserve the overall tonality of your original, which is a little on the darkish side.
I used the same alpha channel for the lens blur to desaturate the background, leaving the foreground color saturated. I wasn't sure whether to neutralize the greenish tint on the fence (which could be from light bouncing off of the surrounding foliage) or leave it, so I left it.
Tough image, visually.
