Wow. This is a simple composition, but very striking. Very zen. I'm not sure about the choice of crop on the leftmost bamboo pole, but I like the image nonetheless.
Nice title....you're right, there is a great harmony to this one (as there is to most of your photos). It's similar to the idea of taking a photo through a window which always adds a sense of intimacy to an image. I couldn't help wondering if darkening the bamboo poles and lightening the background would increase the sense of depth and intimacy.
