Realistic Space Marine Illustration

I'm seeking a talented artist to create a realistic illustration of a space marine from my homebrew Space Marine chapter. The space marine should be depicted in an action pose, set against a detailed planet surface background. The background doesn’t have to be very exotic. I’m thinking even a dense, jungle planet habitat backdrop would be great.

Requirements:
- Realistic art style
- Dynamic, full body action pose or menacing full body relaxed pose.
- Detailed planet surface background
- Experience with sci-fi and military themes

Ideal Skills:
-Basic understanding of the Warhammer 40k universe and the Space Marine Aesthetic (armor, weapons, etc…)
- Proficiency in digital or traditional realistic illustration
- Strong understanding of anatomy and dynamic poses
- Ability to create immersive and detailed environments
