Welcome!! Most excellent choice of icon, as well 😂 I think having some kind of introduction post up is very good, so there is something to look at, if you comment somewhere and curious people come and have a look :D

The snowflake_challenge (a friendly January fandom challenge I warmly recommend, if you'd like to subscribe to that comm, too :D) offered a few tips this year about "Introductions posts", including examples, if you're curious! Though this is great as is, too :D I love your blue theme, it's very peaceful.
