I'm guessing this is meant to be big city? The thing about a picture of a city from high above is that it makes it feel so small.

big city! well done! where did you take it in? helicopter? what's way on top?ocean?

ah, big city.....

Love all those straight lines and square boxes. In spite of that starkness it has a warm feeling owing to the colours. Very nice shot.

Big building in a big city. Was this taken from a really big building or a helicopter?

Pity about the qality, the image lacks definition.

I like this shot. I have similar but didn't post it because, well, the perspective means that it is small. Still a great and well composed shot.
