I love the tentacles. One thing the others didn't mention, and maybe its because I'm incorrect, but it wasn't the feminine aspect of the face that I saw as off so much as that the alignment of the nose, mouth and chin. If you draw the basic understructure of the skull and such it actually seems as if the nose angles to the right of his chin and the mouth sort of angles oddly in between.
Someone else verify or deny what I am seeing.....I've not yet had my morning coffee. Otherwise I agree with most of the statements already made. With 'Opera singing' in the title though I kind thought I'd see a more dramatic arm pose and wide open mouth belting out an aria....he seems slightly passive and not so dramatic in gesture....though in form, the horns and tentacles are rockin.

No light, but rather darkness visible.'
