Worldbuilders with multiple sapient species, what are your favorites and what makes them stand out to you? And which one do you think represents your world best?

I'm making a world inspired by old pop culture monsters, such as the Universal monsters, little green men, H. P. Lovecraft, etc. so naturally all of my races are inspired by things from that area. My favorites are a race of Snakemen inspired by the Serpent People from Lovecraft, mostly just because I like the way I made them look in comparison to other snake people in media, but I think the best representations for my world in general are the species of Insect People I've made.

What about yours?
