A bold and vibrant Chinese internet tech company style poster (inspired by Dianping). The main subject is a real human wearing an oversized cartoon crab costume headpiece, with an exaggerated happy expression. He is holding a giant, over-exaggerated seafood platter (recommended dish) full of crabs, scallops, shrimp, oysters, lobster, all detailed and realistic. Around him, various seafood dishes float dynamically in the air, creating energy and excitement. Above him, add multiple floating user review comments in Chinese, styled as internet "bullet comments" (弹幕) with playful icons and usernames, exactly like the sketch. Below the character, show a bold highlighted section with the recommended seafood restaurant name in Chinese: 海货海鲜码头, and place a large location pin icon next to it. At the bottom right corner, add a small smartphone interface UI with a check-in guide, showing a red circle around the 打卡 button, styled like a real Chinese app interface. Keep all Chinese text exactly as in the sketch. Style: energetic, internet-company advertisement look, sharp bold Chinese typography, bright clean lighting, flat-color vector poster mixed with realistic seafood textures, slightly exaggerated proportions,
