I'm not sure if this is the correct spot, but here goes.
I'm really confused on face proportions. Specifically, how varied they appear to be.
In the example below(I only added the red and orange lines; the rest were already in the image), am I aligning the thirds correctly? I thought there should be more above the hairline mark. Also, when people mark the center line, they always put it centered on the eye, but here it looks to be below the eye. What I would really like is a clear side shot of the bone and eye placement in the socket. Some help would be greatly appreciated.
