problem when comparing face

[cucabr]

I put one more face (my face) in the image bank of the code and I used "face_net_demo.py" for tests, however, the distance is at 1.0380375385284424 (threshold = 0.7)
What can I do wrong? How can I see the validation loss of keras?

ps: in the grayscale image I'm wearing glasses while in the other I'm not.
