Step 1: Loose sketch. In this phase I use green in Photoshop to layout the loose composition. Creating a new layer I use red to trace over the rough sketch.
Step 2: Finalize sketch and add bookplate. In this stage I turn the red lineart greyscale by using the hue/sat in Photoshop. I also add in the bookplate as a placeholder so I know how much space to leave in the final art.
Step 3: Color Mockup. In this stage I shift the hue once more to the proposed color. I've added in the background and mocked in where the binding would be placed to make sure no vital art is covered.
Step 4: Final illustration. In the final stage I use my rough sketch from the previous phase and I trace over it in Photoshop. Unlike the sketch phases which were all about composition and blocking in this phase I am trying to add detail, depth, and volume to the scene.
