For the bottom one, each of the foreground rocks on the bottom one were on separate layers so I can make them visable or not, or even move them around if I want, by clicking on their layers. I made it a full painting without the rocks just in case I needed another generic cave setting. I also added the green night fog on it's own layer as well in case I didn't want it. That's the beauty to have all these layers for each painting. I can change things easily without much muss or fuss. This background took the worst hit as for all that work that no one will ever see. Maybe 10% of it was left to see once all the characters were added, but like I said, I can change the color of the cave to blue or something and it could be the Batcave!
