Pastel Minimal Birthday Setup with Banner

An airy, minimalistic indoor birthday scene with a clean, modern aesthetic. White walls and a light wood floor bathed in soft natural daylight from a window. In the foreground, a small cluster of pastel balloons in pink, mint, baby blue, and lavender tied with a delicate white ribbon. A simple ‘Happy Birthday’ banner strung across the wall in an elegant, clean script. A slim white console table holds a tiny, understated cake on a pastel stand, with nothing else cluttering the space. Negative space is emphasized, shadows are soft, and the color palette is muted and calming. Photorealistic or high-resolution digital art style, focusing on minimalism and calm, airy vibes.
