This definitely reminds me – in a very good way – of the Discovery One spaceship of the very-original 2001: A Space Odyssey movie. A craft that never intended to be a warship, and never intended to be able to “land.” Nicely done.
Overall, the modeling is rather simplistic - not a criticism, it’s the nature of what you’re targeting to create. But you’ve done great with the materials, lights, and comp - such that the simplicity of the model just ceases to be a factor.
Thanks! Didn’t think of the Discovery One when I made this but now that you say it I see the resemblance. I actually drew inspiration from the ISV Venture star in the movie Avatar, various artworks and a ship I made in Kerbal Space program haha.
