For the ear I took a selfie of my own as a reference photo. Ears have dozens of valleys and chills in them so I tried to show that with my value. I made a rough outline of the ear and very light sketches of the different areas. The inner aand bottom areas were given the most shading while the areas that rose up were given more value on the edges to simulated a 3D aspect.
For this one I made the outline of the lips as well as the texture of the lips by make lines on them. To prevent it from looking like hair I used a 6B pencil to darken them up and shade around an area of highlight on the lower lip. The rest above the lip was done by just shading.
For the nose the nostrils were the only thing that I drew using lines. The bridge of the nose and the edges were done just by shading alone. Overall, this I felt was well done for a practice but different value change could have made it more realistic.
Depsite the eyes being the hardest to re-create, I really enjoyed drawing. For this I made a football shape and altering it into the shape of an eye. The next thing I did was make circles to create the iris, cornea, and the eye ball itself. after shading in the eye and add highlights I made eye lashes and shading outside the eye to simulate how our eyes are sunken in on our face.
This full portrait was done over a printed out skull in order to practive proportions on a full human skull. The mouth, nose, and ears were easy to get the proportions down right but the eyes were slightly disproportionate wiht the face. The shading was also off and the hair could have been done better. Overall, the eyes and shading are my most important things to work on. The hair is okay but could be improved.
