You were almost there! Make sure to carefully follow the line of orientation and the structure of the face. It becomes especially tricky when placing the nose. The main points that need to be aligned are the upper lip’s central crease (the philtrum) and the center of the chin. Then, the nose should be added as if it were resting on this facial plane. I hope this was helpful to you.
Thanks for your tips, I didn't even notice until now, I'll try to learn from this mistake and I appreciate your time to answer this feedback
Hi! I was thinking that maybe you felt my answer didn't really address your question. Your question was about shading, but it's actually form that gives proportions and creates the sense of three-dimensionality. Once the form is established, shading becomes much easier to apply. Then other questions come into play: where does the light source—or sources—come from? What do you want this light to convey (joy, sadness, mystery, etc.)? I suggest continuing to work on form first. Happy drawing!
