A pixel city is essnetially just that. A city made of pixels. The idea is the city starts as an empty "block" which is in isometric form. From that you can build whatever you want on it but only under one condition: It has to be built pixel by pixel. no fancy photoshop effects allowed or anything like that. You can however take shortcuts such as using the text function in photoshop but ONLY if you know how to make it look like it was made pixel by pixel.
A few custom rules I have added"
>> Dont oversize your buildings as to "hide" others in the city.
>> You can attach two or more blocks together into one for a large building, but again, follow the above rule.
So lets get this started shall we? The template block is below:

As more entries are received, I will join them together and post the city here in this post.
P.S. Make sure to keep the empty areas of the image transparent to make them easier to join.
