Transform Sketch into T-Shirt Design

I need a professional designer to convert a personal sketch into a medium-sized, realistic black-and-white image for printing on the center back of a T-shirt. The design should be realistic in style and monochromatic, aligning with the preferred black and white color scheme.

Ideal Skills:
- Proficiency in graphic design and digital illustration
- Experience in creating designs for apparel
- Strong understanding of translating sketches into digital art

Please provide examples of similar work in your portfolio.

I have attached my last T-shirt project for style reference.
