Custom Phone Case Design

I need an original graphic that can be printed on a phone kılıfı. The idea is to combine a clean, modern look with a touch of playfulness that will appeal to a young, style-conscious audience. You will be working from a blank slate: there is no existing brand guide, so colour palette, typography suggestions, and layout choices are all up to your creative direction as long as the final artwork is production-ready. Deliverables must include a high-resolution, print-ready file (preferably PSD or AI with layers intact) plus a flattened PNG preview on a standard phone-case mock-up so I can visualise how it will look in real life. Please highlight your experience designing phone accessories or other small-format consumer products. Sample images or live links are welcome; I’m especially interested in projects where you adapted a concept to curved or irregular surfaces. If you need any additional measurements or template specs, let me know and I will supply them immediately.
