If you look at the video on his tiktok, the boroughs are divided into rectangles with clear shifts between the borders. For the boroughs at least, it seems like he repeated a style for a given rectangle and then switched to a different style for the next one. The result is more impressionistic, it doesn't seem to be accurate down to the building level.
It's possible his Manhattan is more accurate, I didn't try to check.
