The left and right arrows, or space, to go through slides. This is all my artwork, I used Autodesk-Sketchbook as the drawing app.
Slide 1: Skitch Sketcharoo Slide 2: Block our basic colors Slide 3: Add large blocks of color. (Blush, clothing, etc) Slide 4: Highlights and some finer details Notes: I like to leave my sketching lines over my final drawing, it makes it look more...drawn? I dunno. You can always turn down the opacity, or change the color, but I like it red or blue, most of the time.
