Act as a seasoned retro-futuristic concept artist with 10+ years of experience in blending vintage aesthetics with sci-fi elements. Create a highly detailed MidJourney portrait of a [gender-neutral] pilot wearing a [1950s-inspired chrome helmet] with [goggles perched atop], set against a backdrop of a [nebula-filled cosmos] or a [retro rocket cockpit]. The helmet should feature intricate [brass dials] and [worn leather straps], while the pilot's expression exudes [determined confidence] or [playful nostalgia]. Use a color palette of [metallic blues, burnt oranges, and muted golds] to evoke a mid-century sci-fi vibe. Add subtle lens flares and grain for authenticity. Focus on dramatic lighting to highlight the helmet's reflective surface and the pilot's [sharp jawline] or [mysterious smirk].
