Begin adding more nuanced areas - refining lights and shadows, beginning to add details like facial features and background information. While you're working on details, don't forget to still mind the big picture, as this will help you keep the lights and shadows you've developed so far.
Tips:
Complete the "underpainting" before working on the lights and shadows, and details. Focus on the big picture before getting distracted by the little things like nostrils, pupils, highlights, etc. This is in case you need to change proportions or tone - that you won't have to redo what you've already done.
In between now and October 22nd, work on your collaged piece. This is the portrait you'll work on for the rest of the course. As you're collaging, remember to squint to see lights and shadows as this will make the biggest difference in the realism of your portrait. Rip or cut your paper, or play with a combination of the two. The more time you spend on your artwork, the more refined you'll be able to make it. Try to work on your piece at least 2 hours outside of class.
Finish your collaged portrait, created by cutting shapes with scissors / xacto knife.
Choose a portrait you want to work on for the rest of the course.
