プロンプト

portrait of a charismatic, red-skinned demon in a digital comic-book style with subtle pixel-art influences. He has vivid red skin, short tousled black hair, and a neatly trimmed goatee. He wears a stylish black suit jacket over a dark collared shirt. His expression is a confident, roguish grin, equal parts charming and dangerous. One eye glows an intense crimson red while the other burns with an icy electric blue, suggesting supernatural power. The lighting is dramatic and neon-infused with a casino penthouse atmosphere. The composition should be close up avatar portrait framed like a visual novel character icon
