These images feel more like sketches than finished images to me in the sense that I had imagined something different from the image.
Curses Shane - you've made me think - and it's getting late! (I think best in the mornings, you see)
This is a problem I have faced, hence my expending the thinking time on it
I don't know what your vision was, but here are some of my random thoughts, in no particular order, just things I might try, for culling later if they didn't work, as Geoff and John do.
I assume you can approach it, wander around it, etc.
My thinking is that we need to simplify the composition; have as few different textures and tonal as possible.
Therefore I was going to suggest getting lower, to avoid seeing those background trees on the horizon, if shooting the scene as per the mono version.
This also means trying to capture it with a 'flat' sky, either full cloud or 'clear blue'.
Other ideas to be creative with this subject (some might be impossible as I cannot judge the size of it too well)
Shoot in amongst the branches with a wide angle, looking for 'creepy' compositions of branches that envelope the viewer. Use DoF wisely, but experiment.
To shoot from high angles, if you have one, put a camera on a monopod, start 10 second timer, hoist it aloft holding the bottom until the shutter fires. (You may want to use a P&S for this last idea)
Shoot macro of the texture of the leaves or bark. (probably not what you had in mind as we'd lose the context)
Shoot it at night and light paint it with flashlight/torch, or strobe/flashgun. (US/UK terminology), perhaps using colour gels or even candy/sweet wrappers.
Shoot at odd angles - I
never do this, so it would be an adventure for me
Splash it liberally with water, or apply at carefully chosen points, and shoot the glistening drops
Hope that helps, I'll let others think of creative PP ideas for taking the above suggestions a stage further.
However, none of that sounds much like ...
I had envisioned more muted lighting and a blank sky for a more ethereal, almost foggy, feel.
Cheers,
