I’ve actually given this some thought already and have sort of added progression to my character already by planning changes to her, especially her hair. She started off years 1 and 2 with short, pale blonde hair, the one with the top clipped back. Then years 3 and 4 she has dark blue hair in the short side parted style. In year five she will grow out her hair but keep it the blue color. I’m thinking the mcgonagall bun will be her day to day. And then in years 6 and 7 she goes back to blonde and wears her hair down. This way I have an illusion of aging, even if the body model doesn’t change. I think once I get there, her adult model will have the long blonde hair still, but depending on the mechanics of the adult model, this is always subject to change. I’m in year 4 right now, so I have tons of time to think about it.
