When we’re putting in the lines for eyes, nose and chin, we want to maintain the curvature of the sphere, cause the front of the face(and back), are more rounded than the sides(that’s why they’re chopped off). The angle of the jawline is roughly halfway between the chin and eyeline. These are the few pointers I have for the Loomis head. Keep going! Your art journey has just started. I encourage you to be brave and start plotting in the features, as they do help with getting used to the general proportions of the face, especially when done from reference.
