Sketching a series of tubes

Hey all,

Sorry for the big delay in response. Finals got the best of me for the past few weeks. I’ve been practicing and I think I am starting to make progress. Here are some of my practice sheets. I threw in some practice doodles that look at prismacolor marker caps. A couple weeks ago I got my hands on a copy of Sketching: The Basics. Wow! Great book. I love the fast and loose approach - leaving in construction lines, using light grey marker underlays, not being afraid to change a drawing in progress, so many different material approaches.
