Bill took a picture of an intersection while I was driving.  Then, using that image, we outlined it on a layer above in Gimp and painted the trees.  I then used the Magic Wand Tool to select the sky and fiill it with our color of choice, using the Paint 
Bucket Tool.  Then, once I was satisfied , I blended the layer I just made with the original photograph.  Then, we merged the two images together and saved it as a JPeg File.
