The title fits the content in a very well matching way, Shyamal! The lighting alone, under the low lying clouds makes the image look melancholic, but also very thoughtful in its own way. I see some very silent kind of nostalgy here, that gets enhanced by the surface of the water and the far horizon. The sea and the sand appear heavy and loaded, and the now dead trunk with its roots out of the earth lies lifeless and reminds of times when it was living. I see some wish to regain something of which the spectator knows that it lies for ever behind the borders that cannot be crossed. But the wish still exists - and thus melancholy?
Technically spoken there are also very strong leading lines here. They are not expicitely present but they are created in the mind of the spectator by perceiving the convergence of the two planes of reference for perspective, between which the spectator stands when looking at the image, and which seem to bracket the spectator very firmly, in an almost asphyxial way that makes breathing heavy. It creates the impression of a prison, a place that one can't get away of, amplifying thus the concept of that border that cannot be crossed.
I add an attachment for demonstrating better what I mean with those implicit leading lines.
