My latest obsessive Chicago background piece. Pen & Ink, 22"x 10", ~30hrs. Minimal touchup and graytones in Photoshop.
Extrapolated the angle from panoramic photos taken from Navy Pier (off the page to the left) and the observation deck of the Hancock Building (tallest building in the foreground), and a little help from Google Earth to help with building placement.
Taken from my comic, Paradigm Shift
