[Thor]loki and [The Avengers]Loki

I saw this magnificent painting on Tumblr (someone may have reposted it without your permission; I couldn't tell if it was authorized), and I was just stunned by how sexy, tragic, and symbolically powerful it is. So I was wondering if it would be all right to write a short fic based on it, and link to the picture in the fic. Thank you so much!
