I like the colour version best.

I like it because it is quite a busy scene and I think the colour makes some sense of it and makes it easier to look at.

B/W works well for the mountains and sky, if the town and boats were not there this would be my choice. 

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.
