Damn was this tedious! Though it's digital art, most artists know that when working to achieve real-world perspective (further away = smaller), it's usually not as simple as copy+paste. It may have been easier if the city was rectangular, but I was dead set on it being circular.
So I started writing a fiction that portrays Newgrounds as a city in cyberspace. I felt it would assist in helping my readers to envision story events if they could see what the city looks like. Also, in the process of creating the city, I have developed more possibilities for plot direction. This is the basic layout for part of the city without any buildings added in. I just felt it might be a good idea to show this because once the buildings are put in, alot of ground won't be visible.
