.Movie Night at Batman's House.
The picture on the left was posted by Jay Fosgitt, aka "Fourpanelhero," and I loved it right away. He did such a great job of not only setting up a funny scene, but really capturing excellent expressions on all the faces.

Almost immediately, I got an image in my head of ways that shading could be used to layer the depth of the image a little more. Within 5 minutes of seeing the original, I was already tinkering around in Photoshop to see what I could do with it. My main goal was to give more of the impression that it is nighttime and the only light sources are the television and the moon outside. With the exception of the moon and sky, I stayed true to all of Jay's original color choices. I just darkened things substantially and then added some highlights. I had a lot of fun with this, and I thank Jay for creating such a brilliant picture in the first place.
