Love the detail on some of these Sci-Fi wallpapers, would love to see them as an actual bedroom wallpaper!
I think there’s something wrong with your links, the one on this page says 89 instead of 90 and when I tried to extract the files I only managed to get one out
The set should be fine, I extracted the right files. Maybe try downloading with a different browser?
Thank you
