This is beautiful in a really rich and creepy way. The color palette is earthy and warm and keeps trying to lure me in, while the scene itself is just bloodcurdling. The little tableau with the wine and cherries and pomegranate, the gilt-tipped lion's paw and the bloody-looking knife, hearkens back to the golden age of still life paintings - but it's balanced by the horrific scene in the upper corner. The cracked glass is an inspired touch, and the fact that the victims are two men and a woman - i.e., some version of the Trio being sacrificed to the basilisk - is just chilling. That, and the combination of sexual violence with sadistic death. *shudders*
Harry's expression, and the languid way he dangles the chain, is awesome. I love his smirk, the ease with which he reclines on the piled furs, the clenching of his toes with self-satisfaction. Voldie/Harry's so fucking pleased with himself here. And there must be something wrong with me, because the way Snape rests his blind face against Harry's thigh and clings to him so submissively, either helpless and enthralled or just utterly defeated - GUH. And Harry's large hand, slightly out of proportion, the weight of it bearing Snape's head down and pressing it to his leg - it's so emotionally twisty and terrible. It makes my toes curl. Poor doomed Severus. His half-shadowy, blindfolded face is a thing of beauty, and so is his right hand, curled around Harry's thigh.
I'm totally drawn in by the softness of the fur, the smoothness of their bodies, your use of highlights, the implicit narrative, and the seduction of the color scheme - but in the end, it's the excruciating, awful eroticism of this moment that's irresistible. Highest marks, and much messed-up love for this.
