ปลาคราฟคอสมิกในเนบิวลา

A surrealist digital illustration with a low-angle upward perspective. A [giant colorful koi fish] swims gracefully through a dreamlike cosmic nebula, surrounded by vibrant cosmic dust and floating translucent bubbles. In the center foreground stands a small human figure seen from behind, calmly looking up at the colossal koi soaring overhead, as the creature looks down toward the person. Dramatic scale contrast, glowing celestial lighting, ethereal and dreamy atmosphere.
