Okay, bin 'em both. For an estate agent, the most important thing is to show a sense of trust and reliability. To do this, the viewer must be on the same level as she is. The second is right out because the camera angle is low causing her to lok down on the viewer which places them in an inferior position.
The top one is closer, but she's still slightly above the viewer. Raise your camera angle ever so slightly and pose her so that her eyes are closer to level; not level but closer. Also bring her chin down a bit, and bring the key light around to the right just a bit to avoid that hard shadow caused by her hair. I would also bring the light in a bit closer and drop the power to reduce the specularity. It might be worth dropping your fill by 1/3-1/2 stop just to get some shadow, but that's something to experiment with.
You're already head & shoulders above most social media profile shots, but why not go the extra mile?
