Nice natural framing. I'm not sure if you used a Polarizer Filter (CP), it doesn't look like it, playing with this will give you a bluer sky and would have made the Jefferson Memorial Pop out more, also give the water a less grey look. See "The Repose of a Serbian Miner, 1894" photo in this challenge, I'm pretty sure they used the CP filter.
Right then, joke's on me as I now have to plough through 564 images and bump them all (yes, all of them) up. There'll be a third run through for fine tuning.
A bit chocolate box, but well balanced and composed. 7
