Photoshop practice 1

I found this image through google earth, after that I used PS add some filter effects (Blur and Stylize). At first, I just used one colour for this picture but later I found it would be more special if I add more colours to emphasize and separate each part. When I apply these effects for this photo, it looks like a thermal blueprint plan of a city but you can use them for other kinds of photo, the result can be interesting. Here is my work :)
