The portrait depicts a lush, tropical garden.  Birds of paradise soar over a crystal waterfall, while jungle animals rest peacefully by the shore of a tranquil lake.  Despite this, there is something deeply, horribly WRONG about this picture, but you just can't put your finger on it.  It is as though there is some distorted, hideous atrocity right in front of you, hidden inside the beautiful images.  Your mind reels, a bad headache setting in.
Something is written beneath the portrait.
