Nice treatment of a classic subject Greg! It looks almost over exposed, but that gives it a very graphic-artsy look. Nice contrast, and wonderful perspective/composition! I especially like the near-far thing in the first one. Is this with your 24mm?
Greg, they're all overexposed. But, you know what - it works very nicely with this subject matter. Good job here. By the way, the lower the iso number the more exposure, the higher the number less exposure. Since it's an arithmetic progression, halve the iso for 1 more stop exposure and double the iso for 1 f-stop less.
