With the first point I might agree, though I did use some real data when [modelling this alternate Mars](https://hardeshur.blogspot.com/2022/07/introduction-ii-brave-new-mars.html?m=1). But the second one is definitely a stretch as it‘s already clear by the title how this relates to Mars and this is meant to be a throwback to genuine speculation people had about the red planet in the [1950s](https://youtu.be/mQ-T5VEueW0) and [60s](https://www.nationalgeographic.com/magazine/article/explore-space-carl-sagan-mars-martian-archive). There‘s also nothing in the sub‘s rules that prevents posts about Mars in a cultural context. I even asked the mods for permission before posting

Should be in r/SpecArt. Nothing in here is scientific, or even Mars related.
