This was originally done to be used in layers for a vertical parallax effect when scrolling down a webpage.
As everything I'm posting, it's part of the work I'm doing on our upcoming game called Plague Huntress.
Honestly, every second I can spare for some pixeling is being funneled into helping out with the game's art, so there you have it. | 
Thank you everyone for the kind words.
@Stickman I'm still a newbie in dithering and was afraid to use it throughout the image, so I decided to just take a chance on the buildings instead of using another color. But you're right, it's not in harmony with the rest of the enviroment. Thank you for the feedback!
