I have not really any clue how to create and especially how to care for such a side. DA is big, here you don`t have to do anything, but of course views here doesn`t give you any benefits.
with the copyright, well don`t know. This comics haven`t much to do with marvel`s version anyway...maybe just Lokis hairstyle is similiar to the one in the movies (in the marvel comics he looks totally different anyway)
I guess the problem is here that he's using copyrighted characters. If he wouldn't use the MARVEL versions of the characters he could earn money with these kind of comics but since they're copyrighted I don't think it's allowed.
naah - parodies and works of fiction are hardly out of "fair use" terms. Look at video game review shows - they literally show every possible spoiler.
Also how are Norse mythology copyright ? Savu would have to slightly change the appearance of the characters to distance them from the comic characters of the same name, but overall he can laugh off anyone who claims Thor or Loki are copyright to Marvel.
