Okay, so this took me forever and I am done now. Basically, I really liked this idea, so I hopped on the bandwagon. BG is a mix of paintovers and filters, but other than that everything is all mine. I'm finally happy with how Scar's effect turned out, yay! Anyway, thanks, bartonesque, for the awesome gifset.
Edit, because I wasn't super clear before: The casting of this picture came from a gifset by bartonesque on tumblr. So anyone wondering why I picked a certain character to be a certain Avenger, I didn't! I just followed bartonesque's ideas.
[Image is a redo of the Avengers movie poster. Disney characters are in costumes that are trying to be a mix of Avengers and Disney costumes, they do all right I think. As in the gifset above, Thor is Hercules, Cap is Aurora, Black Widow is Mulan, Hawkeye is Robin Hood, Iron Man is Kuzco, Hulk is the Beast, Fury is Cobra Bubbles, and Loki is Scar, who has been placed large and central in the image, fading out towards the bottom.]
