I like the art. And it worked well, I think, the way it ended. I think that having that long walk (which seemed odd to me to be blank at first) and then going back to the 'real world' where things are close but it still took that long walk to get there worked well.
I'm in a lot of pain today, too, so this was a bit too relateable :P I hope you have some less painful days and more energy days ahead.
