I started with the buildings, and did a mix of vertical lines, horizontal lines and diagonal lines, so that the buildings touching each other all have lines going different directions. This way it helps separate the different buildings, although I also did a tight zig zag down the edges or outline of each building, as well.
|notice on these buildings -- diagonal, vertical, opposite diagonal (following the|
edge of the slanty line up top on that building), horizontal, vertical, and so on..
|front (in progress) and back|
I love that I can look at the back and tell where the buildings are!
