I really didn't like the look of Alistair and Teagan when I finally met up with them late in the game so I decided to try to fix them up a bit. Neither came out as well as I'd like due to not having a toolkit but they are still an improvement.
Note: I've only played through the Alistair King scenario so I don't know what he'll be dressed as or what have you as a drunk or warden. The pics I've taken are all from the king scenario, but I used the drunk look for the drunk pic. Currently the King and Warden Alistair look alike.
Just put this in the override directory and your good to go.
I included all versions of Alistair and Teagan in the .erf.
