Hi @Haizhen Wang. I think your notes, and the drawings in them are good! The most important part of your drawing training is practice. After you´ve made these notes, make sure you do the assignments, so that you can apply what you´ve learnt. The assignment for this part of the course is to: Draw the Nose Take a picture of your own nose or find some good photos online (get some with clear light and shadows). Follow Stan´s step-by-step lesson to complete the drawing. Rewatch the lesson to review all the anatomical details. Those take a few times to understand. (https://www.proko.com/course-lesson/how-to-draw-a-nose-step-by-step/assignments ) If you haven´t done the assignments for the eye yet, do that too. Hope this helps and good luck :)

Hi Erin! I don't have a reference to compare to but I think it would help to first draw (lightly) the underlying construction of the nose. Think about the keystone shape and the main ball-like cartilage of the nose and how the centerline flows over the forms. Hope this helps!

wow they are really good! I would only try to work on the shading. Maybe put clear reflected light on shadow areas and some highlights to describe the form better :)

Very nice sketches! One thing that could certainly help is to establish guidelines for how the nose should sit on the rounded front plane of the face - on the second drawing, for example, it feels to me a bit like the left wing of the nose (to the right of the page) tilts down slightly too much. Another thing that comes to my mind right now is that maybe you could try defining beforehand the ethnicity of the person you're drawing, then you'd already narrow down a bit more how to solve the anatomy specifics of that nose in particular. Hope this helps, keep it up!
