My goodness. Bringing two of my favorite things together, absolutely MARVELous, like a Dream(works). XD sorry, couldn't help it. I really love the hilarity that comes with combining the road to el dorado to Thor and Loki. Another! (If you get the reference, your as cool as a bow tie.(a reference inside a reference, I am on a roll XD)) keep calm and draw on!
I can conjure up no other possible ways for me to love this more. The set up and punchline are great and as usual your art style looks magnificent.
If there's anything to be said of Loki, it's that he is quite good at "delivering" on his promises, whether or not the deal always goes as intended. Sure he got Asgard into several dire situations, but he generally managed to help them out of it too.
