One of the ideas I had for a theme was overpowering cities, concentrating mainly on buildings and positioning the view of the photo to make us feel belittled.
These are a few of my favourites:
I really like the first one, but I don't feel the others are as powerful. Not entirely sure whether to carry on with this theme or not.
I've edited them in photoshop, increasing the contrast a little to make it that extra bit powerful. I've made them black and white too, just as a personal preference.
