Create a soft, modern cover image for a Food Delivery App Usability Case Study that matches a minimalist, pixel-inspired portfolio design. Use light pastel colors with blue accents and soft shading. Depict stylized smartphone screens displaying simplified food delivery app interfaces inspired by DoorDash, UberEats, and GrubHub — including icons like a food menu, delivery map, and order tracker — without using real logos or branding.

The composition should look clean, approachable, and cohesive with a portfolio featuring cartoon-style illustrations, rounded visuals, and a calm, tech-inspired aesthetic. See more
