A confident, muscular woman with an undercut pixie haircut stands in a grey sports bra and black shorts against a dark textured background.

Create a high-resolution, full-body portrait of an androgynous, tomboy-inspired woman with a short, sharp undercut pixie hairstyle, emphasizing her muscular physique. Use a balanced composition with her centered in the frame, capturing her from head to toe against a neutral, subtly textured background. Render her with a cool-toned color palette—muted blues and grays—to highlight her skin tone and athletic build, with soft, natural lighting that accentuates muscle definition, especially in her arms, shoulders, and legs. Incorporate film grain reminiscent of Kodak Portra 400 for a warm, cinematic feel, and include slight vignetting to focus attention on her face and upper body. Her expression should be confident and relaxed, embodying her gender-neutral, tomboy aesthetic, with details such as visible muscle striation, toned abs, and a broad chest, while her hairstyle adds a fierce, edgy vibe that emphasizes her masculinity and androgyny.
