Mermaid with Harp in a Crystal Cave, Undertale Style

Seated on a rock in a glowing underground cave, a smiling mermaid with long wavy hair plucks a harp decorated with shells. She's dressed in a beaded necklace, a pearl headband with a small seashell, a scalloped shell top and finned ears, and her spotted tail spirals into a curl at the bottom of the page. Tall crystal clusters line the cave walls, icicle-like stalactites hang overhead and bubbles drift up through the water. Six round-eyed fish swim close by, with seaweed and little shells at the foot of the rocks. Big smooth areas sit next to fine details, which makes it a good match for kids who enjoy longer projects. Try soft purples and pinks on the crystals and a shimmery teal tail. Grab the free PDF for a relaxed afternoon.
