Strange! The image looked blurry in the preview, but when I viewed it at full size, the blurriness didn't increase—if anything, it seemed to lessen.

Actually, I had to soften the dark areas a bit, but not to the point of looking like plasticine. The sky is a bit murky and there's a lot of noise. So, super-sharpness just isn't possible here.
