I really like the idea of delaying the return of Ben and then ending the movie with/near that scene. But you irised the wrong way 😉 (the final shot is supposed to disappear as a small circle shrinking into the middle of the screen). Unless, of course, it was stylistically designed to be that way.
Total blunder on my part, though I kind of like reversing the iris, when timed with the music it does make look like the iconic fanfare is coming at you.
