This is artist Mark Carder’s website and it is filled with information. He has one of the most extensive collection of free videos that I’ve seen, plus Q & A, not to mention free access to his “Full Course” on line. He also has a few downloadable video courses that you can buy (Realism, Landscapes, Portraits). If you’re interested in doing realistic figurative work, this might be a good resource for you. You can also follow him on YouTube.
