What a mystical feeling you´ve captured Dark:) The noise level in the clouds is high, but it actually kind of fit the pic and mood. Kinda looks like a snapshot from an old movie, pretty cool!
I agree with josse that the noise level is high and doesn't necessarily detract from the pic. I might have moved the center subject slightly off-center to the left, but then you might have lost the white break in the clouds.
I like the mood and the graininess of the shot gives an old-fashion feel even though it is of a modern turbine. The back-lighting seems to have given the turbine a light outline on both sides. (Just a bit distracting.) It is a good image.
