I am a keen enthusiast of dawn too. This is my capture. Just wis to make a comparison. Yours is calmness and mine is nervousness. Hahaha. Hope you like mine too.
I started with some unsharp masking with some emphasis on the black and white fading.
Then a play with hue/saturation and lightness.
Used ND Grad and ND Blue filters to punch up the sky and balance it better with the foreground.
Then I used velvia vision plugin to punch up the yellow/green tones and enhance the dynamic range in the darker foreground.
