Here's the best I could do without re-rendering it with a larger area and going through editing it in post again. There's two versions linked:Full resolution (12800x5400) which is technically too large to be practical as a wallpaper (it's also 72MB+).Scaled down to 3440x1440 (standard high-res 21:9 resolution) and at a much more manageable file size of 5MB.
