These are not great images just ones from the scrap bin but as an example here is one with ND grad applied to the sky and warm up grad applied to the foreground. Only did that really quick as an example the sky could be darker :)

And every one said, 'If we only live,
We too will go to sea in a Sieve,---
To the hills of the Chankly Bore!'
Far and few, far and few, Are the lands where the Jumblies live;
Their heads are green, and their hands are blue, And they went to sea in a Sieve.
