Here are the overture and intermission images. Note that unlike your version, mine has a red fade in the black area, which I don’t think is correct. The Overture version was made by a nice redditor in the Photoshop Requests subreddit, and I adapted it for the Intermission image. Mine are also 1920x1080.
The sky isn’t correct, but other elements of this are quite good. I’m already using some minor details from the horses and carriage in an update to my version.
