Flux, latest Midjourney, or even dall-e... I'm still disappointed that 3 of my sci-fi prompts never works (interior of an O'Neill Cylinder, Space elevator, rotating space station). I hope someone makes lora of those one day.
First attempt:

Tweaking to specify spokes around the central axis:

"Create a highly detailed image of the interior of a massive cylindrical space habitat, rotating along its axis to generate artificial gravity. The habitat's inner surface is divided into multiple sections featuring lush forests, serene lakes, and small, picturesque villages. The central axis of the cylinder emits a soft, ambient light, mimicking natural sunlight, casting gentle shadows and creating a sense of day and night. The habitat's curvature should be evident, with the landscape bending upwards on both sides. Include a sense of depth and scale, highlighting the vastness of this self-contained world."
flux kind of got the idea but the gravity is still off.
I think this is the most popular one right now online for Flux.

They definitely struggle with getting the land moving up the wall and often it treats the cylinder like a window onto earth at ground level but I think with tweaking the weighting or order of terms and enough rolls of the dice you could get it.
