Glad you like the photo - The building's (and grass) look to bright because I had to adjust contrast, saturation and brightness between pictures to get the lighting and colors the same across all of the images. It would be really obvious in some pics that it was a different image otherwise. Still need to get better at that...
Good spot on the building in the background to. From the air, it looks like a giant half-pipe just sticking out of the ground. Thankfully, it's much more fun than a convention centre. The building is called Xscape, and it's huge. Inside is a real snow ski slope, an indoor free-fall flight simulator (Called AitKix), and Europe's largest climbing wall to name a few. It's also filled with up-market restaurants and shops. It's pretty cool - I spend a fair bit of time (and money!) in there.
It's off-topic, but they have a website here if your interested:http://www.xscape.co.uk/milton-keynes
My house is in the row of houses right at the front of the pic, so it's not to far to get to the above from here! Finally, to clear up any confusion for those not familiar with how we do things here (someone's asked already!), Emerson Valley is the name of the estate in Milton Keynes that I live in. No, the name is not made up
