I guess the blocking out of the foreground hills and shoreline was intentional, but for me it didn't work too well. I really like the depth of the background and the detail in the sky though.
I like this but those halos are so distracting :( Also I might have edited the sky to try and reduce the detail and contrasts in it, for me it just makes an otherwise serene shot a bit cluttered.
Not sure about the processing, it's not bad, but I don't tend to like glow like that between the ridges. Might have worked better if the glow radius was much larger, so it spread out the gradient more.
