What models or loras or workflows can help me create doll or toy figures from images similar to ChatGPT or CapCut

I first happened upon these features in ChatGPT and in CapCut and was interested in trying to create something on my own, locally, in my own style. I'm not quite sure where to start though. I'm a bit of a beginner in Comfy and A1111. I'm aware there are some doll style loras out there, for example But, while those loras are good for generating from scratch, I'm wondering how I can do what ChatGPT and CapCut are doing, which is creating a doll style image out of a reference image.
