Hi Ashik,
I like the idea of putting this solitary tree in a flat field of the rice paddy. It would b e great to repeat this in a season when the rows are filled with workers.
One feature that seems to recur with some of your photographs is blown skies. You could try a graduated neutral density filter of else two-three shot with bracketed exposure. Do you know how to blend them? Perhaps you are expert with this! If not ask! Thanks for keeping the EXIF info. That's always helpful. This picture should be finely detailed and therefore taken on a tripod with the mirror up on a DSLR, with the Canon G6, even at 1/640 at f4.0, this needs a tripod and a cord release. What was the ISO used?
Kind wishes,
BTW, Did you increase the color saturation?
