Neon Mobile App Development Promo Cover

[Format] Landscape 16:9 gig cover, glossy neon-lit 3D promo composite. Electric glow, wet-gloss reflections, cinematic rim light on the subject. No watermark, no personal names. [Layout] Full-bleed indigo-to-violet gradient wrapped in sweeping neon light ribbons and a few floating glass spheres. The composition splits left and right: a neon-outlined rounded-rectangle device silhouette fills the right half as a background frame, with a person cut-out standing inside it, while the left half holds a stacked headline. Under the headline sit four neon-outlined rounded-square tiles in a row; beneath them, slightly left of centre, a slim yellow rounded-pill button. A faint grid of app-tile shapes sits far back at low contrast near the top. [Subject] A young woman in a black tailored blazer over a black top, arms folded, waist-up, smiling at camera. She stands inside the neon device outline on the right, cropped at the bottom edge, occupying roughly the right 35 percent of the frame. [Headline] Upper left: MOBILE APP, heavy italic uppercase sans with a warm yellow-to-orange gradient face and a thin dark outline, very large. Directly beneath, inside a neon-outlined dark rounded rectangle: DEVELOPMENT, heavy uppercase sans in flat white with a soft cyan glow behind it. Bottom left: ORDER NOW, bold uppercase sans, dark navy, centred on a yellow rounded-pill button with a thin light outline. [Badges] A row of four equal neon-outlined rounded-square tiles sits below the headline, each holding a platform logo: the Flutter mark as a blue-and-cyan angular chevron; the Python logo as a blue-and-yellow interlocking coiled-snake pair; the Apple logo as a white apple silhouette; and the Android robot as a green rounded mark with two short side nubs. [Mood] Palette of electric indigo, violet, magenta neon, warm yellow and white. High-energy and futuristic with very high contrast; the yellow button and the yellow headline glyphs are the first thing the eye catches.
