Mags are good for shading, and filling, and covers more ground than round shaders. You’ll get more of an even gradient when shading with a mag when you “whip”. I don’t recommend using circular motions when trying to get a nice gradient from dark to light cause you tend to leave what some may call “chew marks”. When trying to get a nice gradient from dark to light, start from the base of the dark area, and whip out towards the area you want to to lighten up. The best way to describe whipping, is having the needle angle, and go in a straight line, starting deep from the base (dark area) then ease up on the needle depth till you come out of the skin (light area). Speed will affect the change in tone, so practice…Hope this helps, and not confuses you!;)
