Final Fantasy Cartoon Art Enhancement

I'm seeking a skilled digital artist who can take my AI-generated Final Fantasy concept and transform it into a high-quality cartoonish piece. I attached the separate images of the characters and I just want someone to make it look identical to them on the big one. AI is obviously unable to make the characters accurate.

Requirements:
- Improve color and shading
- Enhance detail and complexity
- Ensure character accuracy and errors


Ideal Skills and Experience:
- Expertise in cartoonish digital art
- Strong understanding of color theory and shading techniques
- Experience with intricate details and character design, particularly in the Final Fantasy universe
