I was struggling a lot because I didn't want to do anything too predictable. I settled in my mind to do a play on a comic book but I was also having trouble figuring out the storyline. I knew it needed to include a reading component and that I don't like the door to be completely covered so that I can't see out. This meant that the middle area needed to include a reason why it would make sense to be open. I finally landed on using Iron Man because I could add some humor and it would make absolute sense with the character. It took a weekend to get it done but when all was said and done, it fit perfectly.
