It's Mars!
It's a bit like the one I made for the Space Engine community, but that one is fictitious.
If anyone decides to use it, I hope you enjoy!
Oh, I've tested it as an icon, and even though the thumbnail image looks a bit wonky, it looks fine as an icon.
I'd love to increase the color saturation and contrast (even though it probably wouldn't look as natural), but editing webp files is proving harder than making them to begin with. :(
This is amazing work
Thank you!
