I decided to skip small, medium, and large to spend a few more days on huge.
I tried to give it a retro-futuristic look, so I added a subtle grain, and some intense glare. Most of it was compositing, but geometry nodes and shader nodes also played a huge role.
I did use a photo as the background image, I am taking nodevember a little bit more casually than some, and having fun with it. It would be great to make a procedural space background though. If you have any suggestions, let me know!
