Never Let Your Friends Pick Your Costume Watercolor and Ink; 9 X 12 inches; Fall 2006 Prints: N/A Original: N/A This was my Halloween picture for 2006. It's based on an idea that Lily and Peter are both muggles and that Peter has a love of Sci-Fi. I figured if no one but Peter and Lily knew the Star Wars characters, they might have some fun.
