About the artwork
A small, green-clad figure with a leaf-like hat stands within a large, crystalline mask, surrounded by shimmering, fractured light. The mask, composed of dark and light facets, appears to be forming or breaking apart, with sharp, glowing edges. The background is a dark, rocky landscape.
