Ok, showing her (pretty!) face is a good sign, it makes him a witness so less likely for this to be a danger to his health and more likely to be a danger to his wallet.
Or a really bad one, but if she wanted to kill him, this would be a rather weird way of going about it.
He doesn't even try to keep the admiration from his face. She's pretty, she knows it, and now she knows that he knows too.
"Well, this looks too detailed and precise to be a dream. Guess I could be hallucinating or could be gone batshit insane instead, but my mind seems fine. Not that I would know, probably. But I can see in your smile that it's not the correct answer."
"Oh, you could have drugged me. But see above, I don't really believe it."
It's kinda hard to look properly at the sphere around them without looking away from her, and he's super not looking away from someone this sketchy. Plus he doesn't want to look away. He likes pretty women, sue him.
No, there is something else. Nothing he has seen so far can't be replicated with really good practical effects (or CGI, but you can't CGI in the real world), but... why bother?
Stalking. Practical magic. What is he missing?
"Eh, whatever. Can we skip to the part where you convince me to give you money?"
