Realistic Character Illustrations for RPG

I'm in need of a talented graphic artist who can create 1-5 character illustrations for a tabletop role-playing game. The illustrations should be in a realistic style, as opposed to cartoonish or fantasy-centric designs.

Ideal Skills Needed:
- Proficiency in creating realistic character designs.
- Experience with tabletop role-playing game illustrations.
- Strong understanding of visual storytelling.

Please provide your portfolio or samples of similar work you've done in the past.
