Model16000 is trained used D&D character as the class prompt, and for whatever reason it ~ seems ~ to work better for centaurs and aarakocra
Model30000 is trained using all of the images as the class images, and I think it emulates the commission DnD character style better. It works VERY well for most races, though sometimes I have to fight to get aarakocra to not be birds or centaurs to not be horses. Tieflings work great, but reining in their horns can be trouble. There is some bleed through between classes- especially for elf ears and horns. Including elf ears and horns as negative prompts seems to help.
Good prompts to try things out:
[natural colors], full body tiefling (knight), [watercolor digital 2D painting], (strong shading), hard shadows, blurry, elegant, wearing robes, style of (saga comic) Lois van Baarle and charlie bowater and Sui Ishida, messy, disheveled, thick brushwork, detailed face and eyes, concept art
portrait (painting) of tabaxi, de Rivia closeup, suit, collar, formal attire, D&D, fantasy, intricate, elegant, highly detailed, artstation, concept art, matte, sharp focus, (brush strokes), (oil on canvas), hearthstone, art by Titian and Greg Rutkowski and Rembrandt van Rijn and Alphonse Mucha (inspired by Reddit post)
