Let's not forget the Mexican on the left wall, the monkey in the sky, there's also a midget riding a dolphin in the cobblestones. So, now we're up to 19.+ There is a woman and a bear on the left wall(2) +face on the right is kissing another face(1) + tiny face on the right behind column + weird face as of the pig on the left (half of it on the wall, the other on the column) + it's either white mouse or rabbit on the left wall + bird + dog+ in the upper left corner
6+9=15 faces (both human and animal)
