Act as a seasoned graphic designer with 10+ years of experience in retro and vintage branding. Create a high-quality Midjourney logo concept for a [RETRO SKATE SHOP] named [ROLLIN' REBELS]. The logo should embody a nostalgic [1970s-1980s] aesthetic, featuring bold typography, vibrant colors (think neon pinks, electric blues, and sunny yellows), and dynamic elements like skate wheels, lightning bolts, or abstract motion lines. Incorporate a stylized [SKATEBOARD SILHOUETTE] or [ROLLER SKATE ICON] as the central motif, ensuring it feels energetic and playful. The design should work well on merchandise, storefronts, and digital platforms. Avoid overly complex details—keep it clean, legible, and instantly recognizable. Use a textured or grainy finish to enhance the vintage vibe. Provide 3 stylistic variations: one with a circular badge layout, one with a horizontal wordmark, and one with a minimalist icon-only option.
