Transit Architecture Streetwear Tee Mockup

Create a premium mockup of a white oversized streetwear T-shirt. The front features a centered vertical rectangular graphic with an original minimalist urban architectural illustration inspired by modern transit structures. Do not copy or trace any photograph. Use geometric steel framework, elevated rail forms, road perspective, abstract pedestrian silhouettes, a soft blue-to-white sky gradient, muted sage trees, flat vector illustration with subtle grain, and a thin black border around the rectangle. Keep the design clean, luxurious, and minimalist. On the back, place a small black "RAANI" logo centered about 1 inch below the neckline in a modern sans-serif font. Show realistic front and back views with premium fabric texture and soft studio lighting. --hd --profile itw5lbc
