sunset on air

Yesterday there was a spectacular sunset on air over my house.

Such sunsets are possible only uphill like where I live. The sun sets much sooner than at sea which means the colours are more gold like. At sea the sunset would be red and on fire instead.
I'm trying to set something up in order to make the silhouette more interesting: if you have anything to suggest I would love to try it because I get such sunsets at least once every week during fall season.
Thanks!
