This is just a first attempt. I have gathered the sort of images I wanted this pastel glossy style to make and polished them to make this. I may make a future version with even more polish, removing a few objects.

It seems a str of 1.2 is needed to get the full effect.

The LoRa does not use tags, but it was trained on these tags, which makes the effect stronger:

pastel glossy style, stylized anatomy, smooth shading, minimal detail, pastel palette, soft lighting, , v1, a1

To get NSFW images, I added another lora , the Krea2 NSFW KNP, to my workflow

Krea 2 NSFW V4 - v4.3_EXP | Krea 2 LoRA | Civitai

Each example image contains a workflow that can be seen when you get it onto a ComfyUI canvas
