One of the things that I have noted whilst playing skyrim is that everyone body language is the same. Everyone stands the same, walks the same, sits the same etc.

A warrior will walk like a mage, or a young person like an old person and I think that it would help bring out the character in the NPCs if they could have different animation sets.

For example take the following idea's for walking:
Warrior: Confident walk, shoulders back, slight swagger, head level
Mage: Head slightly down (as in thought), long and medium speed strides, slight swagger
Snob: Head slightly up, slowish smaller steps (no hurry)
Average Worker: faster walk, head slightly down, shoulders slightly up.
Old person: Stooped, small steps, slow walk, doddering.
Good looking woman: Head up, shoulders back, swaying hips

Same for sitting:
A warrior should lean back,look at ease but ready.
A mage should sit slightly more straight, but look at ease with their head slightly down (maybe pull out a book to read).
A snob should sit up straight, and look self important
The average worker should lean back or forwards, and look tired
An old person should sit forwards, with their shoulders stooped.

A set of say, standing idle, walking, running and sitting animations for the major different people: Warriors, Mages, Workers, Old people could help to make the people seem more real.

Do you guys think this would be possible or is it too much work?

this would be a sweet addition to the game. someone make it.
