Painterly editorial waist-up portrait of an elderly polar botanist with close-cropped white hair, frost-lined features, and a quilted indigo field jacket, centered beneath arching greenhouse ribs and layered foreground foliage in a windswept tundra greenhouse filled with hardy alpine plants, glass specimen jars, and ice-coated research tools. Tactile brushwork, expressive facial detail, glacial blue, indigo, lichen green, and soft ivory palette, diffused arctic daylight through frosted glass with a subtle warm interior glow, resolute and inquisitive mood, controlled visual noise, no text, watermark, logo, border, UI, or interface elements.
