special, but I like!

good emphasis on the tree using contrasting colours, the black and white on both sides is also good balance, but it depends on what youre trying to say with the picture as whether this is really neccassary.

I've been coming back to this over and over again since the day you uploaded it, trying to think of what I wanted to say, and I think I've finally got it.

At the initial viewing, I was dead sure for about a minute that it was a full size tree growing on some structure in the water. But the line on the wall gave it away, and even now I can still tell how I made the mistake. Very neat.

The lighting on the tree itself is excellent - I love the halo effect. In all, it makes the photo less harsh than your usual shots, and this one definitely benefits from that.
Also relating to lighting, the black all across the left is neat, but it's made better by the streaking of the tree's shadow into it. I can't really decide if this would have been better or not, were there a more gradual transition between the dark and light halves. Anyway, I'd be interested in seeing more concepts like this.

I'm gonna try this style lighting in combination with portraits soon, should be interesting
