Wiry ginger mechanic with eyepatch in a dieselpunk workshop, determined and focused expression, covered in grease and oil, working on a large, steam-powered machine, tools and parts scattered around, workshop filled with heavy machinery and steam, air filled with the scent of metal and smoke, distant sounds of clanking gears and hissing steam, use of 'high resolution', '8k', 'hyper-detailed', 'dieselpunk', 'dramatic lighting' to highlight the gritty environment, 'depth of field' for immersive effect, 'HDR' for high dynamic range
