I like the story so far you have made him powerful but not op yet. We will have to see how powerful you make other magic users compared to the MC. I would say that the House of Undying would target him to find out how he can do magic. He could make friends with the the Faceless men due to having technically passing through Death's realm. Also R'hllor's followers could go either way due to they could see him as the Prince that was promised or an agent of the Great other by bring brought back to life
