Realistic Comic Book Character Design

I'm in need of an artist capable of designing realistic comic book characters, specifically heroes and villains. I have detailed descriptions of the characters that I can provide, so the artist would not need to come up with their own concepts.

Ideal Skills and Experience:
- Proficiency in creating realistic art
- Extensive experience in character design, particularly for comic books
- Ability to interpret and visualize detailed character descriptions
- Prior work with designing both heroes and villains
- Strong portfolio showcasing a range of realistic character designs
