I'm actually currently listening to an audio book of Rhialto the Marvelous by Jack Vance - I didn't get a ton of that atmosphere here, which isn't a bad thing, but I did see some of the other influences well used.
I like the plot hooks you provided, a nice addition would be a very simple astrologer NPC to save the GM a few steps if they'd like to run this scenario. I can't say enough good things about the artwork, just wow!
The Timeline section on the first page felt like a big shift, with a very conversational tone, it might work well presented as a quote or broken up into rumors - the most important piece of information is that a luxury space-yacht has crash landed.
You did a great job presenting the monsters and I liked that each had its own page dedicated to it (and variants), allowing them to be really fleshed out. Great choice to include images of each room next to their descriptions too.
The information on the aftermath is useful and I liked all of the items you presented, The Drill would be epic to use in combat.
