Fuuu I LOVE THAT PICTURE *p* Loki is and amazing character - cause I am Loki Faaan xDDD - and...it is awesome and amazing...I love the colours and lights and...whoa.... I just want that someday.... in the future... I can draw like you XD.... Its just a Dream but ... Okay stop xD I'm watchin you!
I feel like this could be adapted into some Part Mecha-warrior Sci-fi Magic kind of Fanfiction where they, as sort-of-magic imbued brothers, get placed in some kind of cyborg/mecha soldier program (more or less ending up with Raiden-y esque armor/bodies) that ends up in disaster and their separation leading Thor to fight for a band of good guys (i.e. other Avengers) and then a climactic battle with the super-weapon of their enemy, which of course would turn out to be Loki.
Anyway, fantastic coloring, looks absolutely super wicked cool C:
