hey andrea! here are covers for two of your requests, catch the wind and nightmare! (i'm going to try and fulfil the third if possible, but i only had tangible ideas for these two.) catch the wind was relatively easy to make, and i enjoyed incorporating stars and constellations into the cover (even though they don't really look like the ones the eternals posters use😭😭). nightmare was slightly more complicated, but i really enjoyed putting it together! i hope they both work for you.
please dm me for the link to download your graphics. thank you so much for requesting!
