I use chat gpt, and dall e is able to draw centaurs just fine.
To generate prompts I used gpt: fantasy image character generator
But simple prompts like make a centaur also wors.
Here is two example pics.
I did not fully read your post if you wanted it a very specific way, sorry if this was not what you where looking for.

Like the prompt
A centaur ranger | wearing rugged leather armor and a green cloak | holding a simple but well-crafted wooden longbow | full-body idle pose | MMORPG 3D asset | rich colors | dense forest background with dappled sunlight filtering through the trees | youthful, lean, and muscular build | dark brown equine body with white socks | emerald-green eyes scanning the surroundings | quiver of arrows on their back, bone-handled hunting knife on belt | moss-covered ancient stone nearby, deer trail leading deeper into the forest | fantasy setting inspired by role-playing and strategy games.
Generates a low level centaur ranger.
And this prompt generated a high level centaur paladin
A centaur paladin | wearing radiant silver and gold-plated armor, celestial runes glowing faintly | holding a divine greatsword infused with holy energy | full-body idle pose | MMORPG 3D asset | rich colors | grand celestial temple background with glowing pillars and floating golden light | majestic white stallion body, muscular upper form | blue eyes glowing with divine wisdom | gold-plated kite shield with a lion emblem strapped to side | flowing holy cape shimmering with celestial energy | holy sigils glowing beneath hooves | fantasy setting inspired by role-playing and strategy games.
