Hyper- realistic digital art. Close- up. A fiery bull with flames engulfing its body is standing in a dark arena. Macro shot. Vibrant colors and fine details, reminiscent of sculpture. Flames with visible sparks and smoke. Arena with deep shadows. Blazing orange and yellow hues against deep blues and purples, with gradients of embers. Best quality, incredibly detailed, fine texture, realistic fire, flame simulation, abstract expression, complementary colors, high contrast
