The sale price for my video demonstration is on for just a couple more days (goes back to regular price Sept 1), buy now if you're interested!
Here's the final drawing from the video.
This last image is a value analysis that I hope those of you interested in portrait drawing will find helpful: it has a noise reduction filter laid over it to remove detail and texture leaving only the value structure. It's nerve wracking to do a live demo like this one, the video crew won't come back another day if you wreck the portrait being filmed so you have to have some ideas about holding the drawing together. My idea is to carefully keep the value structure organized and grouped for a naturalistic lighting effect that is believable and clear, and that lends strength to the composition. I hope you enjoy the video.
