1. If your characters are always wearing jackets/half off jackets, try adding "off shoulder" in negative prompt. You may further add "jackets"/ "bare shoulders" if the issue persists. 2. Similar as the jacket issue, if you find any elements that are always being generated, try adding them into negative prompt first. The training dataset is well tagged. Therefore AI should be able to remove these elements. Prompts like hexagon and isometric help to shape the gacha splash effect. There are some alternative choices. https://civitai.com/models/13090?modelVersionId=38884
