Community: fanart_recs
Why is it awesome: It's a comm where people sign up to share fanart recs about a specific fandom for a month, and I've discovered so many amazing pieces of art thanks to it! I like how welcoming the comm is, any fandom is welcome. It's very well organised and the variety in fandoms always leads to interesting discoveries or bouts of nostalgia when it's an old fandom of yours :D
