White dog portrait pet-photography

[white dog with fluffy coat] positioned in the lower-left quarter of a vertical 2:3 frame, seen in close-up side-profile that fills roughly half the height and leaves generous negative space in the right two-thirds for the prop and background. The center-right is occupied by [heart-shaped red balloon] tethered by a thin ribbon, placed in the upper-right third so the knot and ribbon fall toward the subject and create a diagonal connection between elements. Use an eye-level viewpoint with tight portrait cropping and minimal headroom so the subject's muzzle points toward the balloon and the center remains visually active. Render soft diffused backlight from [soft backlit window] that fills the upper two-thirds of the frame, producing gentle rim separation and very soft, low-contrast shadows along shapes. Emphasize tactile surfaces with crisp fur texture and a slightly glossy balloon surface, keeping the subject sharp against a subtly blurred background plane. Maintain a neutral-cool overall color bias with dominant deep scarlet highlights, pale warm-gray midtones, and restrained dark accents for contrast.
