500 Volume 3 is here! 500 is a collection of sketches completed over a month as part of a personal challenge by designer, Spencer Nugent. In volume three, he again pushes to practice to the point of discomfort by sketching 15-17 pages a day. 500 is a collection of raw, real and unfiltered sketch content in the style of rapid visualization common with industrial designers. Volume three is a fantastic reference resource for ideas on how to push yourself to level up in your drawing ability.
