I don't think there are that many. I went to trawl for free Elf assets on the assets page, but found very few of them.
I'm a bit more fortunate that I can draw my own characters and photobash my own backgrounds if need be. Maybe I'll put some of the Elves and Elven-inspired backgrounds out as I build my project so others can use them too. Who knows, maybe someone might use them with the other existing assets and come up with something I get to play too. 🥰
