These are the basic shapes that i used to create the scene. I used normal shape tools (not primitive ones). To make the curves i used the selection tool, hovered over the line and dragged. For the bottom left one i held alt and clicked to make another corner.
I turned each shape into a movie clip so that they would be added to the library.
I separated the scene up into different sections/layers, so that some shapes would be in front of others.
This is the scene that i ended up with, it is a spooky house/hotel next to a graveyard. I like the way it turned out, and i like the silhouette style.
