Create a hyper-realistic image of a creature with the wise, penetrating eyes and feathered wings of an owl, combined with the serpentine body and fiery breath of a dragon. The creature's feathers transition into scales down its body, shimmering in hues of emerald and sapphire. The scene is set high above in a twilight sky, with the creature soaring above mist-covered mountains, its wings cutting through the air as sparks of fire escape from its mouth, lighting up the clouds.
