don't have a fixed overall fave but music-wise I've been enjoying a lot of Crosby, Stills, Nash and Young.

art-wise, there's a few on twitter I've been digging a bunch lately.
@/sksn_herb has some great Pokemon gen III stuff of the two trainer characters (I think inspired by the Adventures manga but I've not read that far yet!)
@/tiredhomeboi does a lot of very cute Hunter x Hunter stuff, particularly of Kurapika
@/Rejuvo is nice for very stylised characters through angular shapes and does stuff with characters from all sorts (One Piece, Lord of the Rings etc)
