Grok Imagine prompt: Anthropomorphic gray tabby cat riding a vintage brown bicycle with 'Wien' on the tube and a bottle attached to the frame, dressed in steampunk adventurer gear including a leather helmet with aviator goggles, over-ear headphones, a dark jacket with red strap accents, gloves, and jeans. The cat has orange eyes, a focused expression looking over its shoulder, and is holding a frothy pint glass of beer in its right paw while gripping the handlebars with the left. Strapped to its back is a bulky retro-futuristic jetpack backpack with tubes, gauges, switches, and a nozzle, with small paper notes fluttering around the cat’s ear as if caught in the wind. Background is a serene blue sky with soft clouds. Highly detailed digital illustration in a painterly style with warm lighting and vintage tones.
