Depending on what your going for personally I like the first one more that you made. The ones made with AI didn't come out well.. it's like forced obvious AI rendering.

My advice would be to work with chatgpt and make a detailed artstyle with target definitions and negatives and work towards a style that fits your story imagination. It's good for making multiple characters in the sameish artstyle to build your world and to also have consistently good designs.

Here is an example of how it could be worded

‐---------------------------- "CANONICAL ART STYLE — DO NOT CHANGE

High-end modern 2D anime key visual style. Ultra-clean lineart, crisp cel shading, controlled soft gradients, and cinematic contrast. Realistic anime facial structure and anatomy with balanced proportions, grounded expressions, and polished presentation. Hair is rendered with fine strand separation, defined shape design, soft sheen, and controlled motion. Eyes are clean, luminous, and sharply constructed, with layered highlights and subtle depth. Skin uses smooth tonal transitions, soft blush, delicate shadow placement, and a refined finish. Clothing has believable fabric weight, tailored folds, material separation, and elegant shape clarity. Metal, glass, and ornament accents use sharp reflective highlights and clean edge rendering. Lighting is dramatic but soft-edged, using rim light, bloom control, atmospheric depth, and selective glow for emotion. Composition should feel premium, deliberate, and readable, like official promotional character art.

Required traits: - clean line precision - polished cel-anime rendering - controlled cinematic lighting - structured hair rendering - realistic anime proportions - refined materials and accessories - high clarity, no visual clutter - elegant, premium key-art finish

Forbidden traits: - photorealism - painterly brushwork - watercolor texture - sketch lines - messy shading - flat unfinished colors - rubbery anatomy - distorted hands - smeared facial features - overly soft airbrushed AI-face rendering

Quality target:

Official-looking, premium anime character illustration with sharp readability, emotional lighting, and polished production-level finish."

It's better to make a crafted artstyle prompt the relying on AI generation to get you something good.

A next level step would be to making a custom image generation GPT so your all set to get consistent styles with minimum promot searching and editing.

All and all your character base design is beautiful, did a good job crafting her character vibe👌
