Obese female rogue scientist in a chempunk lab, flabby features, intense and unhinged expression, wearing a lab coat stained with chemicals, surrounded by bubbling vats and glowing test tubes, air filled with the scent of chemicals and decay, distant sounds of lab equipment and experimental creatures, use of 'photorealistic', '8k', 'hyper-detailed', 'chempunk', 'dramatic lighting' to highlight the character's intensity, 'depth of field' for immersive effect, 'HDR' for high dynamic range
