README:
This was trained on top of furtasticV1.0 as I like its level of detail and consistent results. Tags that may enhance your prompt include
"shark girl, shark boy, sharp teeth, fins, tail fin, dorsal fin, striped skin, spotted skin"
Recommended negatives:
"furry, tiger, horns, ears"
(The model contains much of its fidelity for non-sharks as well, so you may need to add at least a few of the above to get desired results. I'll try to resolve this in future trainings to make a more dedicated model.)
If you want more consistent and truly "shark-like" anatomy (albeit at some expense to shading, diversity of results and visual quality), I recommend merging it with about 15%-25% of YiffyMix. (The final two example images are from this mix.)
