Sorry Simon, but drink has obviously got the better of you this time.

Yes, look at the roof - the white house just above that line of bushes. Correct it on that and the water is then level too.

You can see the sheep is also leaning forward on it's front legs. They are the dead giveaway as they should always be vertical. Twist it, maybe 5 or 6 degrees, and it all makes sense then. I put my glasses case under my screen to test it out!

There you go little fella. You can stand straight up now and don't let that nasty Simon take any more photos of you!

Not perfect still, I know. 

By Golly gents, you are both right

I enlarged the pic and the white house is stil under an angle! Time to lay of the booze indeed. My wife tells me it is understandable because I am a crooked person.
