Smartphone displayed against swirling gradient cloud backdrop

Digital render presenting smartphone device against volumetric atmospheric effects. Composition employs radial gradient color transitions spanning magenta to orange spectrum. Background features layered fluid dynamics simulating cloud formations with translucent overlays. Display screen exhibits gradient fill from magenta through purple spectrum. Lighting demonstrates specular highlights along device edges. Color temperature shifts from warm amber tones peripherally to cooler magenta-purple zones centrally. Rendering techniques include volumetric lighting and atmospheric perspective manipulation.
