Style Notes

Cinematic: Film-style rendering — widescreen framing, dramatic lighting contrast, graded colors (often teal-orange), and a sense of narrative in the scene.
Hero Portrait: A single dominant subject shot like a key visual — tight framing, strong eye contact or pose, background simplified so the character carries the image.
Illustration: Hand-drawn or digital-painting aesthetics — visible strokes, stylized shapes and colors, deliberately not photoreal.
Marketing Campaign: Ad-ready imagery: clear product or message hierarchy, space reserved for copy and logos, and a polished commercial finish.
Product Mockup: The design presented in context — packaging on a shelf, app on a phone screen, tee on a model — to preview how it looks in the real world.
Vibrant Colors: High saturation and bold color blocking — eye-catching in feeds, but pair with simple composition to avoid visual noise.
