Create a digital painting of a woman, the ornate supreme demon overlord, with a soft lighting gradient and immaculate shading. The dark colour scheme should feature the empress’ swirling gardens. Replace her ears with black horns. Draw inspiration from the styles of Luke Pearson, Stanley Artgerm Lau, and Lois van Baarle. The artwork should have a sense of global illumination and radiant light, with detailed and intricate environments and micro details. No text should be included, and the composition should be reminiscent of high-fantasy artwork trending on ArtStation.
