An interesting thing about Neo's Semblance, though, is that she creates walls in Volume 2 but then switches to covering her body all the way around in Volume 3, and then it seems to evolve further to perhaps being able to make an illusion clone in Volume 6.

Volume 2

In Painting the Town, when she and Roman make their escape, you can clearly see that the environment around them is also part of the illusion, due to the cracks extending beyond just Neo and Roman.

In No Brakes, when she flees from Raven, we briefly see a flash of light pass across the screen, as if she is erecting a wall or something, just before she fades from view.

Volume 3

Her disguises, obviously.

Volume 6

The Neo that jumped from the railing and attacked Cinder probably can't be much else than an illusion clone because I'm not sure how she could have "vanished/teleported" while still attacking Cinder otherwise. Gray did say that her illusions are physical.
