Create a cozy marker-and-pencil illustration with smooth marker fills and visible pencil outlines. Lines should be slightly sketchy but clean, giving a handmade notebook feel. Use warm, cheerful colors with medium saturation and soft blending. Add gentle pencil shading around edges for depth. Facial features are simple and friendly: dot eyes, small curved nose, and a subtle smile. The overall look should feel casual, warm, and inviting, like a personal illustrated journal page.", "style": "marker color + pencil outline", "lighting": "warm indoor light", "color_palette": "warm mid-tone colors", "texture": "smooth marker fills, light pencil grain", "face_style": "simple friendly features", "proportions": "semi-cartoon", "mood": "cozy, casual, welcoming", "background": "minimal with light hand-drawn accents" } 社交媒体帖子 插画 角色 nanobanana
