You captured great expressions from your "adoptees." While I don't know you purpose behind these shots, I'll try to add my two cents. Fun shots for your memory books of them and for them to remember their time.
For the blonde, the cropping is too tight. We've lost both elbows, part of her right hand, and the top of her head. I don't usually mind close crops, but this left too many pieces out of the from. Bring the elbows and hand back in and then I think the head crop might be OK. But, if you can get it all back, that's even better. Second, the implement she is holding is going straight across the frame. It really crops the frame in half. A better pose might include having it at an angle. Third, her left wrist looks uncomfortable with the hard bend that she's holding.
For the brunette, I'd like to see the entire implement instead of cropping off part of the business end of it. The setting works great in this shot with the background and the worn bible(?) on the counter. If you're going for the pose, have her turn her head slightly more toward the camera so we don't get the nose profile, but instead we look along the side of her nose. This minimizes the size of the nose (which really doesn't matter in her case...it's just usually a bit more flattering for most models) and allows us to see the sclera on both sides of her eyes.
For lighting, you've captured a catchlight on the second girl that makes her eye(s) twinkle. The angle on the face shadows the eyes on the first blocks the catchlight. In this case, I think it add to a "deviousness" if there was a catchlight.
In both of them, their badges are out of context for the location. The setting is rustic and the badges are modern. If you want to do these again, have them take off the badges for a modeling session.
Looks like you had a lot of fun and you have a pair of models who will be game for more photoshoots. The camera likes them and they appear to like the camera.
Thanks for sharing!
