I wish there were a longer/deeper explanation behind the reasoning for this poster, but honestly It was a combination of a few small things. First, it's 2015 and I haven't created something this year yet and really needed to spark my creativity. Second, this has been the unofficial week of Marvel's "Ant-Man" with the release of the trailer, the cover of Entertainment Weekly and the release of the new comic-book... I simply couldn't help designing a poster with a tiny hero riding a flying ant.
UPDATE: So... There was that time that the director of the upcoming movie and the writer for the acclaimed new comic-book series showed love for the poster on Twitter and I went to geek heaven...
