Great photo; love the contrast and think this would work really well as a B&W image too.

I'm a new follower of yours, but I know you're a keen biker, so I'm assuming you take these on your rides.

If so, I think that by placing your crash helmet within the main focal area (on the floor, in the hole of the tree stump @ bottom-right thirds intersection), it would provide a nice contrast of nature/man-made and contrast in textures, from the rugged tree to the smooth helmet. And, if the helmet was brightly coloured, a great HDR shot too.

Just an idea, but I like the shot as taken too.
