Okay, you did it and now we're going to deliver. If you know the song 'When I Paint My Masterpiece' by Bob Dylan, he references the "Spanish Stairs" several times. Now we're going to give you the answers to this challenge. Up on the right side of the church, you can see the sky through the bell tower in the first image. In the second image it's completely blacked out.
Keeping our eyes up on the building next to the church, you'll notice a weird little dome in the second picture that isn't there in the first one. Now take your vision to the top of the stairs. There's a dude looking very relaxed as he takes in his surroundings in the second picture. But he doesn't appear in the first. Last difference is the change in t-shirt color for the man at the bottom left of the photo.
