I honestly like the first one, the second and third she really liked though. Im not a portrait person by any means, so im just trying to learn here.
The first kind of gave me a mystery feel, because that underpass we were in for it was kinda dark, damp, and there were many weird sounds. So, ontop of all that, it just gave me this creepy feel.
The second and third, I don't know why she liked them, but she did so I decided to get some feedback on them.
