Well I love the design and he idea. But I think the shading and dithering are very messy and inconsistent, almost as if you went at it randomly. Some of the shading is very heavy with fat pixels, which I makes it look more low resolution than it is. Also there seems to be some problem with the heater in front, it doesn't have a chimney that goes through the building's roof, so where will the smoke go? Anyway, my recommendation is that you remove most of the dithering, and make the shading consistent. Don't try to make it too "realistic", in stead, try to stylize your image more. And keep up the good work! ^_^
