It would be helpful to post multiple angles or a sketchfab upload would be best.
Good start. The eye area in particular are reading most like christopher walken.
Based on this image it looks flat like you sculpted mostly from a front reference and not enough side or three quarters views. In particular the lips seem like they are drawn on instead of the mass that the lips would have. The cheeks feel like they also don’t have the mass that would be needed.
Overall try to sculpt from multiple angles and make sure to add volumes instead of carving in details. Keep it up you are doing good!
