Realistic Sci-Fi Game Art

I need 2D art assets for a sci-fi video game. The project focuses on creating immersive factory/lab-style machines and props.
The main sprites I am looking for are machines with an input and output that physics items will be passing through.
The total project will consist of 20 machine-style sprites, with potentially more work to follow in future development.

Requirements:
- Props: Create various 2D machines with a consistent visual theme.
- NO generative AI use will be accepted at all.

Ideal Skills:
- Expertise in semi-realistic 2D art
- Experience with sci-fi themes
- Strong attention to detail
- Proficiency in digital art software

Looking for a talented artist to bring my video game to life. Please include a portfolio with relevant work.
