SteamCity

SteamCity has great flow and composition. The arrangement of the buildings and urban spires enable me to imagine that I'm actually there. And I would feel murky and gritty. The sky juts through the smoke and steam in a refreshing way (which makes the piece have a warmth it otherwise wouldn't have).

The environment obscures light and distance appropriately. The buildings in the background are hazed over and I get a good feel of distance because of this as well.

The foreground could use a bit more attention, as it falls a bit flat and it seems as though the perspective is a bit off (see the bridge and the water beneath as an example).

I docked this piece for originality a bit but I understand that it's an environmental concept and I've probably seen a million of these types of drawings for inspiration. And pure originality probably isn't the goal here anyway. Your idea translated well and overall I think this is good work.
