Done as part of a 3 hour class. My current goal is: I don't know! I am an absolute beginner; I'm here to study the basics of rendering

It appears like you are drawing the contour line of the features straight onto head, rather than "building" the face and features, which can give your drawing a flat appearance. Do you understand what you’re drawing and why, or are you just copying the outlines?

It’s important that you try to either find the flow of the forms (gesture) or construct the 3D forms (structure). This requires more effort, more mental energy, so naturally you fall back on copying what you see.

Drawing "through" your figures will help you and your viewer understand the subject better. Keep up the good work!
