Thank you for the advice!

Hey, good work exploring these poses! I would recommend practicing constructing these heads with 3 dimensions in mind. The face should be a plane that is distinct from the side of the head. You're on the right track with marking to indicate where the facial features would go! There's lots of methods to drawing the head, so definitely explore and find the one that works best for you! The Loomis method is popular, and I think it's useful for getting the proportions right. I did a draw over on yours to give a basic idea of how those planes can be laid out. By drawing the side plane as another circle on the side of the head, you can then subdivide that circle and use it as a landmark for laying in the jaw and eyes especially. Keep up the great work and keep practicing! https://www.proko.com/course-lesson/planes-and-forms-of-the-head https://www.proko.com/course-lesson/quickly-draw-heads-with-the-loomis-method-part-1 https://www.proko.com/course-lesson/introduction-to-the-head
