I've had this idea when I was about to landed on Suvanabhumi Airport. The idea was come between me coming back home for good and how the scubadiver descending himself into the deep sea where he could call it home. But it also have some melancholy feeling that you don't know if home is the same or if you will ever ascending up there again or not.
I'm planing to make a few series from this topic, we'll see how it goes.(This one is kinda like WWII poster, Kamikaze style!!)
