HI! I would focus on understanding the underlying anatomy, because theres a lot of points on the face particularly that will always follow perspective, use these landmarks to determine what angle your drawing the face at, the OG had 3 different angles on the face, so make sure to pick one, especially for unmoving parts like skulls or bones. Another thing Im noticing that I think is even more important is your Line Confidence. The lines drawn here are VERY messy and feel very indecisive. It will help you make you find your land marks as well if you keep your lines less shaky, and more confident! I really like the colors and the shading of the face, I think you did that really well! I hope this was helpful! | Artwod Feedback
