I started a new game and noticed that Fenris' eyes are not the beautiful green that I remember from previous play throughs. His eyes are not the only ones that have changed however,Anders eyes are amber around the pupil and have a blue ring around the outside, Fenris' eyes have a dark ring around the outer edge and are a washed out light green around the pupil. Aveline's eyes are like Fenris' and so are Merrill's. NPC eyes have also changed somewhat.
This is a list of the mods I'm using:
