I had the final camera position saved on-drive already, but as I was looking at it I was like "I want the rest of the skyline, the composition's off around that building, feels too empty as-is" pretty much, so I got a second print-screen for from before the camera starts moving. Then I put the two together-- hooray! ...but the aspect ratio was bugging me. So, I decided to go the full mile and just make a full-on desktop-- the original resolution for the print-screens was 720x480, which is what gave me the idea.
