someone standing in the back of the hall to the left... ?

a face on the wall right above the head rest on the black wall... ?

looks like a misty figure on the stairs... ?

I saw the boy sitting back on the balcony about 4 secs. after i looked at the picture. unless that was painted there, there is definitely a boy or male sitting almost with his head in his hands or reading to the top left on the balcony.
