Here's a prompt for a concept art design:
A cinematic portrait of Loona 'Hellhound' in a vintage-inspired aesthetic, reminiscent of Eso Andrews. She's got it, yeah baby, she's got it! The vibrant colors and high-energy composition evoke a sense of euphoria. Loona is dressed in a bold, PoP art-inspired outfit with intricate details on her collar. The dynamic pose captures her fiery personality, as if she's about to unleash her Hellhound persona at any moment. The minimalistic background lets the subject shine, while the cinematic moviemaker style gives the image a sense of depth and dimensionality.
