These are great pages, thanks for sharing! Awesome to see you exploring different expressions, and playing with composition on the page. That layout and note taking for the skull page is spectacular! Keep on doing what you're doing! Here's a lesson from Basics on drawing portraits in perspective and how the features on the face relate to a cube in perspective. This practice really helps when trying to draw faces in different poses, and keeping the features aligned. Keep up the good work! https://www.proko.com/course-lesson/project-portraits-in-perspective
