To give a little background on this race, I wanted to create something akin to the Lizardmen from Warhammer Age of Sigmar. They're different from the Lizardfolk race in Volo's Guide to Monsters in that they're not swamp-dwelling savages, but rather they have a highly ordered and developed (although strange) social order.
According to the unofficial Detect Balance spreadsheet, it seems pretty reasonable, but I wanted to make sure there aren't any unintended synergies (or that it's just out of whack in general).
The description for my homebrew race is below:
Cuetzpali are a race of man-sized, lizard-like humanoids decorated with a frill of feathers around their neck that sometimes extends down their backs or arms as well. They live regimented lives in vast temple-cities following a rigid caste system which dictates their life path from the moment they hatch from their leathery eggs. They worship the sun as the source of all life and spend significant time charting the motion of the sun, moon and stars as an act of devotion and to determine the caste of newly laid clutches of eggs.
Ability Score Increase. Your Constitution score increase by 2, and your Strength score increases by 1.
Age. Cuetzpali reach maturity around age 10 and often live to be 80 years old.
Alignment. Virtually all Cuetzpali are lawful. Their society is bound by a strict caste system and all Cuetzpali can instinctively sense whether a given Cuetzpali is higher or lower on the social ladder than them.
Size. Cuetzpali are similar in height and bulk to humans. Your size is Medium.
Speed. Your base walking speed is 30 feet.
Cold Blooded. Cuetzpali feel emotions less strongly than warm-bloods. You have advantage on saving throws against effects which cause the charmed or frightened conditions.
Slow Metabolism. Cuetzpali commonly eat things which would be toxic to warm-bloods. You have resistance to poison damage and advantage on saving throws against the poisoned condition.
Stargazers. Cuetzpali spend significant time observing the heavens and charting the movement of heavenly bodies. You have proficiency with Navigator's Tools.
Theocratic. Cuetzpali society is based on a deeply theocratic caste system. You have proficiency in the Religion skill.
