Thank you @MichaelD. I ran across an artist on YouTube that has been helpful to me in learning some techniques. Though I'm using photos, I know it will translate into live drawing also. I don't know if you've found him or not. He is Miroslav The Pencil Maestro https://www.youtube.com/channel/UCzgkyglv4yAuQb92jBeizVw in case you are interested.
