I wish more races had an exotic counterpart like the nekos, cows, sharks, bees, harpies/bats, rabbits one of the female demons or a new one(to look like the male one) and most of the hybrids.
As for adding new races my thoughts are snakes/nagas, hare(male rabbit), bears, lion, tomcat(male neko), hornets(male bees), fae folk, sea serpent(shark/naga) sea dragon(shark/dragon), horses, deer, karelian(vulwarg/bear), kobolds, drakobolds (kobold/dragon), jackalope (rabbit/deer), lizardmen, Pegasus (horse/harpy), unicorn (horse/elf), tengu (harpy/demon), phoenix (harpy/seraphim), Hippogryphe (harpy/horse, harpy/minotaur), hobgoblin (goblin/orc).
I can't think of anymore creatures for the farm but for NPCs I can think of is lizardmen chef, futa tanuki the sin of sloth, a druid(the half man, half deer kind), a winged unicorn, hydra the sin of wrath.
If anyone has any other ideas on what they want to see added you can tell me (even though I can't do any thing about it I'd sill like to hear it)
