Coconut furry mix - CoconutUltimateRealistic Review
Overall it's a fantastic model for some good looking characters. I appreciate the clarity that is possible on higher resolution pictures, and the anatomy and physiques on display are often great. I've been able to make some fantastic (and disappointing) pictures using the realism model.
That said, there are some pain points which I feel need to be addressed:
Canine vulva will often be incorrect or upside down. It's like the AI was trained on just the shape seen head on, rather than from a variety of angles including other anatomy. Simple under tail progression: Tail->anus->vulva with the fat end first and the tip pointing away from the tail. Sometimes though it's just an amorphous mass of flesh, upside down, or a quad lobed mass with two Y shapes for the slit. I've included several examples. Amorphous mass of flesh I get, the AI's weird sometimes, but the other issues seem to indicate the vulva was tagged on its own rather than including the rest of the pelvic area for context.
When viewing a canine vulva from the front of the body or above (as in high angle views looking down along the character's stomach) the AI puts the entire vulva on the front of the pelvis instead of just showing the clitoral fossa. Various artists such as Lizet, Santana Hoffman, (occasionally) Truegrave, Yaroul, Lost Goose, Dawn Lux, Tail Tufts, and more draw this appropriately, showing only the top side of the clitoral fossa rather than forcing the full front view. I get it, 90% of canine females are bent over/on their back a presenting themselves, but sometimes people like their foxy ladies upright and doing non-sexual things (or just grinding on their partner properly)... While naked. Look, sometimes girls like to dance naked in the forest and throw leaves in the air during autumn, alright!
On the other half, male canine sheaths seem to be non-existent. Instead, they get a featureless hairy mound and a pair of balls. A canine sheath isn't a featureless pile of hair, or a fuzzy doughnut like some artists (foxinuhbox, Zaush, Eipril) depict. It's a covering extending part way up the abdomen that retracts down to the pelvis as the penis becomes erect. Imagine half to three quarters of your penis foreskin attached to your abdomen while flaccid, then it stretching and retracting as you become erect. Some artists who draw it right (if exaggeratedly large) include: Patto, Cracky, Clockhands, and Kraai Sha
Clothing selections seem fairly limited and/or not well tagged. I've had problems consistently making full torso blouses, full length jeans instead of Daisy Dukes, one piece or bikini swimsuits, hoodies with the hood down, and more. And when it comes to non-contemporary clothing, forget about it. Trying to garb my D&D characters in appropriate attire is next to impossible, with some clothing being a mass of colours (it's never heard of a "tunic" before) and others defaulting to modern equivalents (I asked for a leather backpack, I got a modern nylon camping pack).
Props are sorely lacking. Weaponry of all sorts (swords, bows, staves, daggers, guns), utility stuff (flashlights, torches (the fiery kind), lanterns, quill pens, disposable coffee cups), and sports equipment (tennis rackets, baseball bats, hockey sticks), are all basically unusable or non-existent.
Minor gripe, "feral" does not seem to be a recognised tag to prevent/enforce a more animal appearance in the character. The workaround is using "humanoid" in the appropriate other prompt. So if you specified "anthro" but get a feral character anyway, putting "humanoid" in the positive prompts rather than "feral" in the negative prompts works.
tl;dr - It's a great model for making great naked character with very detailed environments. As long as your character doesn't need a canine sheath with no erect penis, or a canine pussy when not presenting themselves to the viewer.
