 to learn to get more dimension in your art. Try this on for practice. On a scrap piece of paper, stamp or draw an image. Color it in using only grayscale in whatever medium you love, markers, pencils, paints. I'm just using a regular graphite pencil. See how many grays you can get from 100% black through all the mid-tones down to white. Do this with scene elements as well. Keep one of these examples taped up in your workspace to remind you of the power of contrast. It's a great example that'll help you.
