Having decided on concepts I liked, I did some final pieces:
The Bloodroot.
They were the Vetch, a once-passive and flowering race spread across the Eden of a dozen systems.
With the discovery of rich energy and mineral deposits under their planet’s surface which held no true value for the residents, their world was set-upon by neighboring planets bent on cannibalizing all monetary value from their land. When the winter of industrial pollution began to break and light once again reached the surface, a new, less-forgiving race was born. The Bloodroot.
Spreading like a merciless plague across the surface to reclaim their world, the Bloodroot slaughtered millions of industrial colonists in a matter of days. This growth has yet to stop, such that the surface is covered with them for tens of feet, roping across all land and their entire atmosphere is filled with their pollen. Thankfully they have not figured out how to leave their world and spread into the universe… yet.
This is a typical Bloodthorn, an environmentally-mutated Warlord with a Vegetation-based artifact weapon capable of crushing, ripping and converting to nutrition anything it can reach.

The Jun’Korr. A once-great civilization plunged to the depths of brutal, archaic stupidity with the loss of technology in a world now strewn with non-functioning machines made of metal, plastic, glass and rubber.
They have no knowledge on how to repair or engineer anything electrical or mechanical beyond primitive tools and elaborate crap in futile attempts to make something useful.
It’s a long, hard, dumb road back to their former glory and they are heading in the wrong direction.
One saving grace appears to be that a few have garnered abilities to use magic in varying capacities… perhaps due to the pity of some strange diety.
This is a Warlord named Bok. Bok has a Lightning-enhanced artifact weapon constructed from non-functioning machinery and metal. He hits things with it.
He has another large, blunt piece of junk in his other hand too. To him, this is a matching pair.

and The Tchindili
A highly-intelligent and immensely powerful psychic and magic-wielding race of fish.
They have also been described as vicious, arrogant and distrustful.
Their species has been dated to 1.45 million years. Their magical abilities appear much younger than that. It has been hypothesized that they gained their powers from swimming in shoals near sunken magical societies fallen from their planet’s surface. To suggest this to a Tchindili would likely result in one’s immediate death.
Many species appear to make up the Tchindili. Whether this is mutation or integration is unclear. They make a practice of mentally enslaving other aquatic creatures to do their bidding.
This is Ithchatli, a mighty Tchindili Invoker with a Water-based artifact weapon, The Horn of The Unquestioned. It sends forth dense blasts of psychically-formed, magically-charged water capable of vaporizing much of what it hits.

I hope you like them.
For the final, I will be painting and developing the Bloodroot.
Let me know what you think.
