Alternatives to Elfs and Dwarfs

I like fantasy when there are only humans and I like fantasy when everyone looks like and extra from the Mos Eisley cantina, but the middle ground where there are other species but they're basically just grumpy humans with bumpy foreheads or pointy ears just doesn't do it for me.  I've been thinking about how I'd do my ideal version of a fantasy RPG, and have come up with some ideas for alternate fantasy races (I'm thinking about calling them lineages instead).  I still need to come up with in-world names for the different lineages, so for now I'm referring to them by what inspired them.

Dragonfly People

First we have the Dragonfly People (they're sort of dragonfly/firefly/beetle/termite people, really).  They are covered in a segmented carapace, usually in metallic shades of blue, green, and yellow; and have long narrow wings which can be safely folded into their backs.

The Dragonfly People build their castles on floating moats of earth which are the shattered remains of their home moon.  They have great insectoid dragons that they use as war mounts and deterrent from any nosy explorers wanting a peak inside their floating cities.  Each city is ruled by a single Queen and her hive of drones.

If a Dragonfly is seen wandering alone they are either an exiled drone or an immature Queen searching for a place to start her own domain.  The court politics are quite deadly for young Queens waiting to succeed their mother.  If one of her sisters doesn't have her killed the ruling Queen might, trying to hold onto her position for as long as possible.

Once mature and with a land of her own, a Queen will grow into a large wingless worm.  She now spends her time laying eggs and delegating the affairs of her realm.

Moth People

 I also like the idea of Moth People; they're sort of the wood elves to the Dragonfly's high elves.  Since the Moths are also bug people and have an association with the moon, they're probably connected in some way.  They either came from the same shattered moon or hail from their own distant but intact moon.  They are probably solitary or keep to small traveling family groups instead of the large hive kingdoms of their Dragonfly cousins.  The shapes and patterns of their wings vary wildly and they lack the armored exoskeletons.  Their bodies are pretty small, probably hobbit size, but their wings are large enough that they have trouble navigating through crowds and narrow corridors.

Lichen People

 The next lineage are most similar to lichens.  They are each a walking ecosystem, a colony of fungi, algae, and microbes.  The Lichens fill the roll of Ents or Firbolg as the minds and guardians of a forest.  Their form is dictated by the largest piece of dead bio-matter they are currently digesting.  They revere the cycle of life, knowing full well that the death of one being provides to nutrients for the next to thrive.  This outlook combined the decomposing matter that can often be seen intermixed with their bodies has given them a reputation as harbingers of doom, dangerous forest monsters.  Tales of Lichens are told to children to keep them from wandering the woods alone.

One method Lichens have to reproduce is by spreading spores as they wander.  Any fungus breaking down a fallen log or small lichen patch on a damp rock is likely there because a Lichen passed by and gave it notice.  The second way Lichens can reproduce is by breaking off a piece of themselves to become a new independent being.  Each piece that is broken off takes with it some of the parent's memories and personality.  If the pieces get small enough they will lose their sapience, but given time will grow into a full ambulatory adult.  Lichen may meet up with others from neighboring forests and exchange pieces of themselves to share knowledge, or each contribute a piece to create a new being with ties to each wood.

Kangaroo People

Being mammals, Kangaroo People are the most psychologically similar to humans and are often found living in the same communities.  Though they originated from the deserts, they can now be found anywhere humans can.  Their large ears help radiate excess heat and their short course fur protects them from the sun's rays.  This allows them to thrive in climates most others would have trouble even surviving.  Kangaroos can make a good living as desert merchants, traversing the wastes to trade with each of the communities on its border.  The spring-loaded tendons in their legs allow them to comfortably run long distances without overheating or expending too much energy, making them excellent couriers and scouts.

Both the males and females have pouches, and they usually have twins.  The female Kangaroo gives birth after just a few months of pregnancy and each parent puts one of the jelly-bean-sized joeys in their pouch to finish development.  The sharing of parental labor has resulted in a culture without a lot of the gendered hangups of Firefly and some Human societies.

Machine People

I much prefer dying earth science-fantasy to medieval European fantasy, so my world is going to have robots.  In times long forgotten, the Ancients created Machine Gods to watch over them from the sky (AI's in satellites).  In the intervening span most of the gods grew mad from the isolation and fell out of the sky but a few remained.  These remaining gods have managed to reawaken factories deep in the ground to produce bio-mechanical Avatars.  The Avatars are not directly controlled by the full AI gods, rather a small piece is copied and downloaded into the machine body.  Their purpose is to learn what has transpired since the fall of the Ancients, to experience novelty and all the richness of the different civilizations to satiate their loneliness, and to try to gain the perspective of a mortal being.

The avatars are engineered to mimic life and thus are susceptible to most of the dangers of any other mortal being.  They metabolize food to refuel, intake air to avoid overheating, and must sleep.  While asleep their bodies perform maintenance and upload that day's experiences to the Parent Intelligence.  The more an Avatar experiences the more unique it becomes, and the more it interacts with people the more personality is seems to develop.  If a situation is dire, an Avatar may petition its Parent Intelligence for aid, however experiencing struggle and mortality is part of the goal.  The Avatar must convince the Intelligence that the experience gained will be more novel and interesting than the death experience.
