I'm taking a life drawing class this semester so let me pass on a couple things that might help you out. Look for landmarks to align to. For example, the edge of the nose lines up with the inside the the eye. The edge of the right side of the mouth almost lines up with the edge of the left eyebrow, etc. Also, If you look at the right eye no eye lid is present. Also the eye is more towards the left. If you look at the nose the edges are more vertical that angled.
