Well this is from my fanfic 'Possessed' which is sorry not done^^ As for the arch - I really wanted to express Loki's suffering, he's arching because he feels the seal on his back making him feel such terrible pain as if his back is breaking. Laufey is using his magic to penetrate through Loki's soul, tear his senses, drive him crazy, and this all to punish Loki for his betrayal. So that's the scene.
Oh nice. Thanks! The virus of life is very powerful song. I listened to it again and again while drawing this. I pushed my pencil so hard it nearly broke, the feels were great. And when Joe sings "I want to burn your soul." I overheard it as 'I wanna f*ck you', that's what I've wanted to express. And what's interesting about 'burning', Laufey appears here as Surt, the fire giant eovinmg.deviantart.com/art/The… so it just suits perfectly.
