Create a dark and twisted horror illustration that captures a nightmarish scene

Create a dark and twisted horror illustration that captures a nightmarish scene inspired by 'The Wizard of Oz.' In the foreground, depict a grotesque version of Dorothy, her appearance altered to be more monstrous and tragic. She should be bound and restrained, her face hidden by a mask, with a distressed posture as she is pulled forward by chains. Dorothy's attire is tattered and worn, a mix of Victorian-style clothing with a dark, gothic twist, complete with a corset and flowing, torn skirt. She wears heavy, metallic platform boots that add to her burdened stance. Her captors are two malformed, humanoid creatures, one riding on the back of the other. The rider is small, with exaggerated features like sharp teeth, bulging eyes, and a maniacal expression. The mount is a larger, more bestial figure, crawling on all fours, with a rough, lumpy texture to its skin and twisted limbs. The background is a foggy, desolate landscape, with ominous shadows and eerie, dim lighting that enhances the horror atmosphere. The entire scene should feel otherworldly and unsettling, with a focus on the macabre and grotesque elements.
