I repainted the form and the proportions of your oc. Your attention to detail and linework is great, it shows that you have great knowledge on smaller value changes. However the structure of your painting is what I added to the painting. For the proportions I made the angle of the head match the position of the body, and I shortened the nose and eye distance. For the form, I established a clear light source and values. To improve form, you can use form studies of simple spheres and cubes, and learn the planes of the head (Asaro head) And for proportion, you can study the different angles of the head by sketching references and using measurement drawing methods | Artwod Feedback
