I tried something similar and the sky's colours were very washed out, deep solid colours is what you've achieved here; but mine were washed out pales of pinks here I'll show you what I mean:
What am I doing wrong ?
In comparison yours is much better.
I noticed the sky like this yesterday as I drove to work in aberdeen and thought to myself 'if only i had my camera' now I am well annoyed at myself for not having my camera! I guess todays lesson is never leave home without camera!
Wonderful picture by the way.
Awesome looking shot,silhouetted trees work a treat too
....just thinking if it might benefit from a tiny crop off top and bottom ?
