This is an RGBA image with transparency. Create a single charming clockwork snail postman, shown in three-quarter view and entirely contained in a square frame with generous clear space around every extremity. Its small body is made of brushed copper and softly oxidized brass, with two delicate curved antennae, a smooth articulated foot, and tiny believable exposed clockwork gears. In place of a shell it carries a rounded pale-blue translucent glass mail satchel containing three folded cream envelopes tied with a red thread; the glass lets the envelopes and internal highlights remain visible. A tiny leather strap and a loosely curled paper route map suggest a courier setting off on a long journey. Exquisite handmade miniature realism, warm copper reflections, cool glass highlights, subtle scratches, fine thread, clear separate antennae, clean readable silhouette, soft studio illumination from upper left. Only the snail and its carried objects should exist. No floor, ground plane, backdrop, cast shadow outside the subject, lettering, labels, logos, brand, promotional layout, or watermark. Preserve real alpha transparency around the silhouette and through appropriate glass areas; do not draw a checkerboard. The background is transparent.
