Absence comes from the explanatory text. Pity it is not immediately ovious from the image.

Beautiful image. Only I notice a strange effect produced on the top front of the head: it 
seems to me too flatten, maybe due to the position of lightsource.

Good story, although it's not that evident without the description! Nice lighting effect.
