My first time trying to create a character model, I wanted a version of Achilles that's properly compatible with Pony models. I used a mix of art of his normal clothes and his summer skin, so when you generate him without any specific clothing it will generate a mix between the two.

While the trigger word is usually enough, I tend to add these tags too

achilles_(fate), green hair, orange eyes, muscular, solo

Also make sure to add negative text and speech balloon prompt
