First-Person Body Visibility

What I mean by first-person body visibility is that when you look down at the ground in the first-person view, you would see your character's body. If you started walking, running, or sneaking, your character's legs would move as they appear to do in the third-person view. There would be a similar situation with your character's arms. If you don't have anything in your off hand or your dominant hand (or neither, it doesn't matter), you would just see it resting at your side. If you started walking/running, you would see your character's arms moving from side to side, like they do in third-person. You would also be able to see the rest of your body (except for your head, obviously). If you started to turn either right or left, you would see part of your character's shoulders.

This is just a minor detail that could be added in order to add a bit more immersion to the game (not sure if "immersion" is the correct word here). Currently, the first-person view makes your character seem like a floating head with part of an arm(s) attached to it (at least that's what it looks like to me).
