Hi Rajan,
I really appreciate BYW renditions. However, I am wary of just removing the color information. I'm a strong believer in mapping the hues to tones that allow one to better appreciate and enjoy the nooks and crannies, the grittiness and texture of rocks and lands masses in a way that color might not, by itself allow.
I have looked at the color rendition and feel that there may be a considerable room for further mining of the potential impressiveness of your interesting wide angle landscape of this unusual lake and surrounding volcanic hills.
I'd encourage you to continue to work on this image assigning different selected colors by suing filters or else by selectively processing for each interesting color to maximize the features that that color might show when remapped to tonalities only. It could be just my monitor, but it does seem to me that the rocks and base of the clouds have very little dark detail and tonal variation. In fact, different areas of green in your color version are just shown as black with no relief or shapes now appreciated. That's a pity. The B&W version should enhance and provide even more detail to the differences one can already see with color.
