Here are some samples of doodle sheets that I frequently do before I start any drawing...it is a chance to warm up before a study session, leading to a finishing session. I am still trying to bring the control of my rendering up to par with those illustrators that I really look up to. I feel pretty good about the control I have when it comes to pen renderings, but I still feel a bit clumsy when it comes to charcoal.
The bottom sheet are studies of other artists, with exception to the top figure 2nd to the right; that is a photo reference from some art pose book or something. These are all my attempt to try and learn something from truly talented figurative and classical artists.
