Now we can start really assembling our scene. I laid down my background first, by dragging and dropping it onto the first layer and then locking the layer; I've decided that Lex likes to race cars, and just used a piece of related artwork that I drew a long time ago for the background in a comic panel, resized to fit the canvas and saved as a low-quality JPEG file to keep the file size down.
I'm going to reassemble Lex on different layers now, like stringing a marionette together. To start off, I'm going to place his torso on a new layer, and drag it about utnilt it's positioned roughly where I want him to be before locking the layer so that I won't accidentally click and move it anywhere while working on other layers. (You can see that because I used transparent GIFs, it blends seamlessly over the background with no white space.) This is our base that we're going to build on. Looks a little creepy sitting there as a headless, armless trunk, doesn't he?
