I have a community for my music project, but in my experience most project sharing on the Fediverse occurs on Mastodon. There are a few Lemmy communities for production-related discussions but they don't get much traffic or visibility.

Mastodon facilitates producer talk very well. From what I've seen, it also works well for visual artists. If you don't have an account then it might be worth signing up and checking it out.

At the same time, it would be great to have more sharing and discussion occur here on Lemmy. I'm always happy to see others' work, even if they are just beginners.
