This is fun. I look up the scene on the Internet to see about color, etc. but am not always enlightened. Some artistic liberty is called for, particularly when there is little color or contrast. However, some are "dark" in tone and color, so must remain that way to reflect the story.
Foundation paper piecing is one of my favorite techniques. The 7" (finished size) blocks can be made in a couple hours or less, but this 7" x 23" one took a few days. It has lots of itsy, bitsy pieces.
