@moonrabbit Different people have different experiences on BlueSky, but unless your art is particularly interesting/novel, you probably won't get a whole lot of engagement without interacting with others.
Feeds can be useful for getting your posts "found", and can help get more eyes on your work, but you'd have to put in the work to find appropriate Feeds and do whatever is required to get your posts to show up in them. Feeds are mostly maintained by individuals, so they can come and go in terms of popularity.
