Some races I’d like to see.
1. Half-Elves
2. Mer-Folk
3. Fairies (shorter elf base)
I would suggest nymphs but you could technically just use the elf pack for that. Halflings and gnomes might be interesting too. As well as other types of anthros like wolf anthros.
Perhaps even an alien pack, anything from the weird and creepy to otherworldly beautiful. Like for example the aliens in the movie Avatar, not them exactly but something similar?
