great timing/composition. Nailed the monk (?) right as he was in the perfect part of the frame. The perspective lines all draw the eye to him, he's nicely framed by the window, creating an interesting dark subject, light background contrast. The horizontal green strip, I think adds, even though conventional analysis might say it's distracting. It nicely breaks the image up in a subtly organized way.
The steam rising off the bowls (I'm assuming some sort of warm traditional meal) is a very nice, subtle layer that rewards those willing to give more than a casual glance, the "viewer's share" as some might call it
It's one of those images that succeeds because it hits multiple levels:
1) interesting subject (to westerners at least). Not completely foreign, but some novelty does remain.
2) strong graphic composition. you hit all three main points: placement/arrangement, complementary lighting, appropriate color rendition
3) subtle details that reward you for continuing to look at it.
4) has a story that's just vague enough to let me wonder what the subject is up to. It is neither confusing nor too blatant.
