Your race is really basic, although they got a powerful healing feature, the fact that it only deals 1d4 for that much healing mean you could just bite your friends, heal a ton and use the Life Transference spell to give even more health back, which just creates a ridiculous loop that makes clerics look like chumps.
You also forgot to give them proficiencies, dark vision or any other trait that makes them stand out, maybe look to the Dhampir race for how they should heal from blood, maybe the Leech-kin gain proficiency in Survival or Medicine, which would certainly fit their flavour.
I don’t want to offend you but it’s pretty imperfect (they can’t even swim lol).
I need advice for how to edit it to make it better or more fair
EDIT: I just realized I forgot to put its name here omg it’s called “Leech-kin”
