An ancient tidewatch shrine shaped like a resting sea turtle

An ancient tidewatch shrine shaped like a resting sea turtle, for a blocky fantasy game. Give it a low, broad silhouette, a characterful small head and stout flippers supporting the shell. The shell carries a weathered little stone lantern tower, visibly built into it. Blue slate, pale limestone, sea-green moss and a quiet moon-white light. Paint the large surfaces by hand with flowing stone grain, worn carved tide marks and convincing shaded recesses. Make the back and underside as considered as the front. One cohesive editable asset, with no scenery or text.
