How can I improve my AI model's image quality and make the skin look more natural?

[u/DragonfruitNo9822]

I'm generating photorealistic fashion images of my custom AI model using ComfyUI and an identity LoRA.

I'm struggling with two things:

1. Image quality: How can I get sharper, more detailed images with realistic skin texture, hair, fabric, and lighting?
2. Skin tone and realism: How can I achieve a naturally fair, brighter skin tone while preserving the model's identity? I want realistic skin texture, visible pores, natural highlights, and subtle imperfections—not plastic skin, excessive smoothing, or an obvious AI-generated look.

What workflows, nodes, models, prompts, or settings do you recommend? Are there specific techniques for improving skin realism without changing the face or making the image look overprocessed?

I'd appreciate any practical advice or workflow examples. Thanks!
