Design an intriguing and thought-provoking illustration that explores the concept of 'What is Real.' The scene should blur the lines between reality and illusion, inviting viewers to question their perceptions. In the center, place a figure, perhaps a person or a silhouette, standing at a threshold between two worlds: one side represents a vivid, hyper-realistic depiction of everyday life, while the other side showcases a surreal, dream-like landscape. The realistic side can feature familiar scenes such as a bustling city street, a serene park, or a cozy home interior, rendered with fine detail and clarity. In contrast, the surreal side should include fantastical elements like floating islands, upside-down buildings, mythical creatures, and abstract shapes, all rendered in a whimsical and imaginative style. Use a palette of contrasting colors--muted and natural tones for the realistic side, and vibrant, otherworldly hues for the surreal side--to enhance the visual distinction between the two realms. Incorporate subtle details that challenge the viewer's sense of reality, such as objects from the surreal side appearing in the realistic side and vice versa. The overall composition should create a sense of balance and tension, drawing the viewer into the central figure and the question they represent. The art style should be detailed and evocative, with a mix of realism and surrealism, to effectively convey the duality of perception and reality. --ar 7:4
