I don't know why I don't like Lois with long hair. A lot of her appearances have long hair, some pretty definitive too like the animated series and Margot Kidder but I don't really like those. Well, actually... I like the animated series, but somehow I don't like it in the comic as much.
I never actually notice the violet eyes, but I'm picking that anyway because there's already so many dark hair blue eye characters. I'm not opposed to brown either.
