love #2, the light in her face, the clothing. She's very pretty, and you did a good job. I'm not sure I like the house as a background.
I don't really like the first one. Looks more like you working on your techniques than a picture of Katherine.
I'm for the second one as well but with the same reservations as the above mentioned. Perhaps a different crop if you have the room.
Lightening up her eyes would give it a bit more impact. You did very well with the lighting.
