I turned our images into B&W versions in photoshop so you could see the effect - notice how the mood seems to change...things look a little historical or vintage. This is something you can explore with apps from your camera's/phone - as most of you know. Remind me to ask what kind of computer access you have.
We use collage, contour lines(outlines), patterns(like the ones we've done in our doodles), and text, as ways to explore and layer to create contrast and value within each of our 'Scapes.
I'll bring in my example to show you what I mean. I am tracing my hand right now from my cartoon. I want to collage it, and I am also thinking about painting around the characters in my image with energy lines or something to represent their superpowers or maybe just their thoughts - while keeping in mind that I am creating 2 different atmospheres and therefore a different story for each 'Scape.
