 Here is the first, unaltered image that I started with. |
 The first thing I did was add an adjustment layer and give the city a purple glow around the edges. |
 Then I added a filter to the city, giving it glowing edges. |
 After using the lasso tool to select everything but the city, I added a new adjustment layer to turn the background edges red, as opposed to the cool blue. |
 Now is the time consuming part, coloring the city piece by piece. |
 Here is some more work as it gets done. |
 Here is some more, slowly filling in the dark edges. |
 This is the finished city, with red showing the spaces of the buildings facing to the right and yellow for the spaces of the buildings facing left. |
 With the city finished, I can move on to the areas around it, and paint the forest and hills in front of the city green to make it seem more natural. |
 The next step: adding color to the lake in front. |
 The next thing to color would be the sky. |
 The last coloring item is the sand on the shore of the lake. |
 I added another adjustment and color balance layer to show off the blues and contrast the color more. |
 I changed the color of the forest to something less washed out here, attempting to make the city the main attraction. |
 I added a few lines to the buildings to give them more texture and depth. |
