**This is a basic sketch of how I usually draw human faces: it may vary for you depending on artstyle and skill level.** You are able to adjust the guidelines to your liking to create variety within the faces and character you draw! For example, you can lower the line below the nose to change the position of the mouth and jaw. You can do the same with other lines.
This was really random but I decided to do it to prove to my followers that I am alive!! I may make other tutorials in the future.
