Create a premium 3D Roblox shopping trolley/cart skin called “Arctic Titan.” Use the uploaded reference as the main shape reference and keep the trolley clearly recognizable as a shopping cart. Do not completely redesign the silhouette. Give the trolley a powerful frozen/ice theme: primarily dark steel and icy blue materials, with white and light-blue frost accents. Add thick stylized ice armor plates around the existing basket frame, reinforced corners, and chunky frozen-metal details. Add sharp but clean ice crystals growing from selected parts of the frame and front bumper, making the cart look like it has been frozen over. Add subtle icy-blue glowing lines inside some existing bars and around the wheels, plus a small amount of cold mist/frost particles. The glow should be controlled and not overly bright. Make the wheels look heavy and rugged, with dark metal rims and icy-blue details. Add a small frost/titan emblem to the front. The final model should feel massive, powerful, rare, and expensive, like a high-level legendary skin called “Arctic Titan,” while still being a functional-looking shopping trolley. COLOR BALANCE: 55% dark steel, 25% icy blue, 15% white/frost, 5% bright cyan glow. 3D MODEL: clean hard-surface geometry, chunky stylized Roblox proportions, optimized game-ready mesh, clean topology, separate materials, simple readable shapes, suitable for Roblox Studio, no background, no floor, no character, no text, no watermark. Avoid: completely white/bright blue models, excessive glow, giant ice mountains, giant spikes, wings, flames, extra wheels, unrealistic vehicle shapes, excessive tiny details, or changing the basic trolley silhouette.
