Republic Plaza

Very cool. I definitely love the look of it; the snow really fits in with the mood you're trying to capture.
I usually avoid any sort of suggestions/critiquing, because these look so professional you definitely know what you're doing, but I thought a short note on tangents might help?

So yeah, a few of the pictures in this series do that thing where if foreground and background elements meet fluidly and meld, it messes up space and depth a bit. I definitely notice it on the left side where the railings meet continuously and then their snow blends with the background snow, which causes that kind of space-bending effect. I'm not saying I'm an expert-- I only noticed because it's definitely something I do a lot accidentally during the design phase.

Anyway, these are all really awesome-- I've always liked cityscape pictures. Really interesting take on it. Usually people go dirty+cultural+diverse or clean+orderly+grid, and you sort of have a cool blend when you get snow in to break up those grid lines.
