Hi Kiran, I too like the layered dunes quite a bit and the pano crop works perfectly for this scene. I think I would prefer this scene without the human also. Maybe you could clone him out for an alternate version if you are not opposed to doing so. Nice capture!
Nice image here Kiranbhai - sorry for the delay in responding.
I like the layers and the monochrome treatment (though I might play with more contrast personally, and with a bit more tonal range ie blacks darker and whites brighter?)
I am with Robert...human okay, I like images better without them, but sometimes they really do help to achieve that sense of scale as we never really know how big a rock or tree is, but we know how large an average human is
