I am trying to draw TES races. But human races are pretty hard to tell apart. I would like to discuss, how different faces of races differ from others races currently of how they should to be better distinguishable in the future.

What I am puzzled by most right now, is how to make imperials and nords look different from each other. I am looking for the most stereotypical features. Bretons I myself am not too worried about as I have other plans for them. But I am not disencouraging anybody from discussing them.

What I already have thought out?

Nords - rectangle or oblong faces, face is longer than it is wide, powerful jawline, cheekbone line is high and more towards the ears.

Imperials - round or heart shaped faces, face is longer than it is wide, softer jawline than nords, cheekbone line is lower and more towards nose than ears.

Reguards - oval or diamond faces, face is longer than it is wide, strong jawline, cheekbone line is lower and more towards nose than ears.

Bretons - I won't start digging out their facelines. I would take the medium of imperials and nords and then the medium of elves and then the medium of these mediums and I should get bretons.

Beasts - they can be easily identified, so I am not going to list out their face features. But feel free to formulate your opinion if so do desire of course.
