I guess the best time and reason for getting into hot air balloon would be to shoot the long shadows. In absence of that it just only remains as a perspective.
Love the scale, angle, pattern at the center and the crop ! Square works very well here Srini. Opening darker region a bit more might add further. Thanks for sharing.
I just love the view from the top, the angle especially. I second Aditya's suggestion, you could try opening a little and bringing the zebras to the left bottom corner. Thanks for sharing.
