Style Notes

Anime: Japanese animation aesthetics — clean line art, large expressive eyes, cel shading, and scene tropes drawn from anime rather than photography.
Cute & Playful: Rounded shapes, big eyes, candy palettes, and toy-like proportions — the visual language of mascots and sticker packs.
Fashion Look: Editorial fashion styling: garment detail and fabric texture take priority, with model poses and lighting borrowed from magazine shoots.
High Detail: Pushes the model toward micro-texture and fine rendering — pores, fabric weave, surface wear — at the cost of a busier image.
Illustration: Hand-drawn or digital-painting aesthetics — visible strokes, stylized shapes and colors, deliberately not photoreal.
Interior Space: Room-scale scenes with coherent perspective, furniture styling and light sources — architectural visualization meets lifestyle photography.
Soft Light: Diffused, low-contrast lighting — gentle shadows and flattering skin tones, like window light or an overcast day.
Typography: Text is part of the artwork. Modern models like Nano Banana Pro can render legible styled lettering, but keep the exact wording short and quoted in the prompt.
Vibrant Colors: High saturation and bold color blocking — eye-catching in feeds, but pair with simple composition to avoid visual noise.
