Strange. Admittedly, the puzzle does have a sort of visual issue–the pictures that I’m using are facing one way with their bodies and looking another way with their heads. I suggest using the sprites as a better hint.
Don’t forget that you need to activate the four pedestals, too. Some people have forgotten the E key (legitimately).
If you just want a solution, the one provided in the Solutions section of the walkthrough will work, unless something’s gone wrong with your particular version.
