Kind of an AU Idea... - I'm sure, if Zack would've gotten to show Aerith the Sky, he would have wanted to make a picture- so they'd never forget that moment.
Oh and, yes. Aerith's eyes are closed. It's kind of a.. 'heat of the moment' picture. And people don't always have their eyes open, you know..
