천문관 티켓
GPT Image 2· Image
Design a celestial keepsake background inspired by a planetarium ticket: a domed star theater rises beneath a sweeping Milky Way, with tiny silhouetted visitors entering through glowing doors. Use a narrow portrait composition, deep cobalt and violet gradients, pinpoint stars, a crescent rim of warm gold light, subtle vintage print grain, and a clean lower band kept free for ticket details to be placed afterward. No text, no watermark.
