Adrian, I love it, beautifully composed and nicely processed.
If this is your first dawn image then I can't wait to see them when you get some practice.
I find once you start with astro photography using a DSLR, it's only natural to venture into main stream photography as well.
Actually the two complement each other and you learn a lot about colour and composition, not to mention post processing.
One small suggestion on this image would be to boost the colour levels slightly using maybe the curve function if you have PS or equivalent.
Looking forward to more from you.
