This is a scene that only few of us are likely to ever see with our own eyes, Moni, so that alone makes your photo stand out.
The framing of the palm leaves is very nice, too, but what bugs me about this photo is the fact that the very man's face is a little blurred. Now that you call your photo "Old Man On Tree", one expects to SEE the old man - and a little better.
But I understand that this apparently was a spur-of-the-moment photo, one that cannot so easily be repeated, for you had to see the scene, frame it, and take your photo... and for that it is a memorable one!
