If I could critique with one world it would be: Amazing! Unfortunately I can not do that. The penciling you did is amazingly done, the only thing I would like to have seen is a little bit more blending, but the piece is still beautiful with out it. It makes you think of how Loki wishes to be seen as the powerful sorcerer that he is and not just in Thor's shadow, or seen as just his brother in anyway. To me your picture symbolizes the internal struggle Loki has with himself. Its that struggle that makes him try to put his own mark on the realm, whether that be Asgard or Midgard.
