I like that you chose to use a limited colour palette. I think the blue tones used completely encapsulate the coldness and otherworldly feeling about these creatures and the bleakness of their environment. I also think it enhances the horror. When I look at this I can see why they became the stuff of northern legends in the story. The details in the bodies and faces are extremely skilfully rendered, it really gives a sense of coldness and majesty. All in all it is a beautiful piece that shows great talent and skill. I am a huge game of thrones fan and seeing that it inspires beautiful art like this makes me very happy
"So fades the great harvest of my betrayal. Your nobility has blinded you, as ever. R'hllor left little to chance, didn't he? Turning my own creations, my own army, against me. But what hubris to think he could protect his pets from me forever. Time was your ally, human, but now it has abandoned you. The Others...have returned. This tomb, is now yours."
