This is only really quick play around so would not consider it finished. What I was thinking of was less blue so I have used color balance to add yellow + 20 Green +5 Red + 5 all to mid tones. I was trying to make the green more the colour of the leaf segment that comes from bottom right corner to centre because that one is not reflecting the blue from the sky.

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.
