Mike, nice start on that layout. If I may, however, just a suggestion to improve the scenes. Tone down/blend the bricks and motar lines on some of your buildings with several dark washes, so that the mortar lines are much less obvious. In the real world, on older brick structures, mortar lines aren't very apparent at any significant distance unless a section of the brickwork has recently been pointed-up. Don't fret about it, though, it's a typical error that most modelers make.
By example of how to make things look closer of the prototype, look at the weak motar lines on the brick structure in the foreground at right to see what I mean. With age, the color of the brick generally stains the motar, giving it a hue not greatly different from that of the brick, plus there's a buildup of dirt and grime.
