Hello hello! Great workout! You started with a solid base, only needing a few tweaks with proportions. When marking face elements,we usually use eyes as a measure. The total head width is approximately five eyes wide. The eyes are placed midway between the chin and the top of the skull. Approximately one eye-width separates the eyes. The nose's base sits midway between the chin and the eye line. The mouth is situated between the nose and the chin, approximately one-third of the way down. The pupils and the corners of the lips frequently line up. Usually, the ears are positioned horizontally between the bottom of the nose and the brow line. And lastly we have hairline, located approximately 1/3 of the way down from the top of the head to the eye line. These are standards created for idealistic face but since every human head is unique,its important that we observe references from real humans. Having measures in mind and understanding how each element behaves in different perspective views, can help us out with creating different faces. Hope it helps | Artwod Feedback
