Where do you get your inspiration from for specific ideas?

Movies, museums, books (remember those?), google images, concept art, my grandson (kids are a gold mine of things you would never dream of) and friends on my Discord server.

I recently did the models for a sci-fi game (not my usual thing), I watched the entire box sets of Voyager and Stargate to put me in the mood lol

Good luck!

Google image search and pinterest are good enough for anything.
The reason is in the keywords you write.
