木炭上翠綠海玻璃與鸚鵡螺殼

A solitary, exquisitely rendered nautilus shell, subtly textured with faint, swirling patterns, lies centered on a vast expanse of deep charcoal grey. The light source is a single, diffused point originating just beyond the frame, casting a soft, cool glow that highlights the shells pearlescent interior. Tiny, almost imperceptible, fragments of ancient coral and sea glass – a vibrant turquoise – are scattered sparingly around the shell, acting as the sole color contrast. Linear shadows define the shell’s form, emphasizing its simplicity against the flat, atmospheric background.
