Oh please color it! I really like this one and I think some color (perhaps with some shadows as well?) could really make it amazing! Personally I actually prefer zooming in on this one. (and that a good thing )
One little thing, though it's really nitpicking and might just be my personal taste. Something is strange with the crane, I think it's because the perspective on the crane part itself is slightly uneven with that of the ledge beneath it. But perhaps I just think about it because you recently added it.
