here's a step-by-step process of an illustration i made for our office publication about gadgets our oc-workers can't live without. i started with a rough pencil sketch which i scanned...
...then traced in illustrator. i haven't used it in quite a while so it took some getting used to.
i then finished it in photoshop with some shading and adjusted the colors a bit. the blanket and bed cover were so bright, they were distracting us from the gadgets.
