One of the great planning fall backs is, when stuck, just copy the prototype.  I’d been struggling with one aspect of composing the foreground structures.  Specifically, if I put a row of foreground structures end to end on 50th street it would be difficult to see the background structures.  The solution?  Remove every other foreground structure and replace it with a parking lot.  The lot would be framed on both sides by a building.  To make things even more interesting, at least one of the lots could be a container storage yard as per the photo above.
