After Ennis opens and closes a couple of doors, the camera looks out the window (and so does Ennis, in one version of the screenplay).
This makes me think of something. You know how Ennis is always looking out of windows thinking about Jack? That's probably the metaphor they meant to reference in the earlier screenplay.
But when the camera looks out the window, holds the shot, ends on it ... it suggests a bigger, more long-term window looking, don't you think? Especially with the outdoors and the tan and blue colors whatever else you might find symbolic or suggestive of their relationship in the view. By leaving us there, looking out the window, it's like they're telling us that Ennis will be looking out the window forever (or for a long long time, anyway).
And this makes me think of yet another thing. Maybe Ennis' window looking is meant to faintly illustrate his attitude toward the sweet life. When he looks out the window, he sees nature (or at least something closer to nature than whatever's inside the room). And nature represents his life on Brokeback with Jack, where they could live together in peace. So when he looks out the window, he's not only thinking specifically of Jack, but wistfully thinking (maybe subconsciously) of the life he wishes they could have together. And in the end, seeing that out the window, contrasted with Ennis in his closet ... what a powerful image!
We could just go on and on like this forever with this movie, couldn't we?
