Do not merge layers, so we can edit shadow if needed. Shadow should be on opposite sides of light source: IF THE LIGHT IS BOTTOM RIGHT: SHADOWS NEED TO BE TOP+LEFT of object IF THE LIGHT IS TOP LEFT, SHADOWS NEED TO BE BOTTOM+RIGHT of object IF THE LIGHT IS LEFT, SHADOWS NEED TO BE RIGHT of object IF THE LIGHT IS RIGHT, SHADOWS NEED TO BE LEFT of object (These are for all images) PART 2 OF PROJECT —REALISM OF SHADOWS AND ITEMS SEE INSPIRATION :) 1.
