Well ... listen to Elsa, obviously.
The way i feel about rules is the same way as many express on this forum, they are meant to be broken. So, both eyes in focus, yes, for formal portraits. For other types, i support your breaking the rules. I also really like the third portrait, it captures her joy and isn't "boring" in order to have both eyes in sharp focus. I like the other two also BTW, i wouldn't change a thing about them. I do support Frank's wish for more context though.
I'd say you already know quite well how to shoot portraits (and other types of photo) and you have enough baggage to start playing around with the rules.
