Using the quick select tool worked pretty well. I did make a couple mistakes when I was selecting, but those were easy fixes. I think the most challenging thing was changing the colors, but once I got the hang of it it was easier. Something I might do different next time would probably be setting up the pictures in a different pattern. I used the quick select tool, move tool, gradient map feature, and the layer merge tool. All of which work pretty well once I got the hang of it.
