I've seen some great images posted here. I have an idea for one, and considering that I'm not all all familiar with Bryce, I thought I throw it out to the masses. When I was in college a friend of mine was majoring in art. One of his assignments was to demonstrate perspective and shadow. He did a pencil sketch that I thought was great. The scene showed a city skyline in the background on the horizon line. The foreground was a desert with plants, rocks etc. In the air over the city was an A-4 Skyhawk aircraft pulling up and away from the city. In the center of the city was a huge nuclear mushroom cloud, a result of as bomb the aircraft had just dropped. All the items in the foreground cast long distinct shadows as a result of the flash. As I recall he got a B on the project, the comment from the teacher was that it demonstrated the assignment but she didn't like the subject. The guy who did the original was named Jesse Evans, as far as I know he's never done commercial art work.
