A completely legit question asked by one of Karl's students. Sometimes its impossible to tell. It a tough subject to breach because I think often times people are anxious to see if they are making progress. My understanding of drawing is that its a craft and perfecting a craft can take years...And even then progress isn't guaranteed.
Here are a bunch of sketches from Karl's Thursday night Fundamental Figure Drawing class. Karl said the biggest thing I need to work on is structure. Its true. Most times, I get so carried away with all the playful flowing curves of the muscles and fat that I forget to add the points of articulation and bone structure to hang them on.
