Astonishing image Simon ! You have used this concept with imagination and your own unique approach. I don't think you should hold back from posting it in your gallery on my account, or anyone Else's for that matter. The concept I had seen before and as such mentioned it when I posted, yet each image is as unique and individual as photographers are. Just because someone has photographed Eileen Doonan Castle before does not mean that no one else should. Each photograph is a unique capture of how the light was recorded at that moment in time and should be valued as such.

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.
