Here is a industrial sketch I did of a Sander, Followed a tutorial by a Youtuber named Spencer Nugent. Used ellipses and smooth strokes to get the overall look of a roundish object. Hardened some strokes to give it more shape.
Used Prisma markers Cool Grey 70% and Blush Pink to highlight the light source and again to show the overall roundish shape and model of the object. Used darker strokes on certain parts of the object to show shadows.
