Definitely not a comic. 'American Gods' is famous for its literary form as a novel, which explores deep themes and characters through written narrative rather than comic panels.
Not at all. The art styles, storylines, and the intended audiences can vary significantly between American and Canadian comic books. For example, the publishing industry and distribution methods can also be quite different.
To draw in the American comic style, you need to master perspective, shading, and color choices. Learn from the works of famous comic artists and practice a lot. It's all about developing a unique style while adhering to the key elements of the genre.
I don't think there is. Comics with African American 'Fly Girls' are quite rare and might not have gained significant popularity or visibility yet. But you could keep an eye on emerging indie comics for potential ones.
