Phi Hành Gia Phi Ngựa Giữa Vũ Trụ Sâu

Painterly surreal oil painting of [an astronaut riding a horse through outer space]. The astronaut wears a bulky white EVA spacesuit with a backpack life-support unit, glossy gold-tinted helmet visor, subtle red and blue suit accents, thick gloves, and boots, seated upright in a brown leather saddle holding red-brown reins. The horse is [chestnut brown with a white blaze and white lower legs], captured in dynamic mid-gallop facing right with raised forelegs, wind-swept mane and tail, detailed bridle, and an expressive realistic head. The setting is a deep navy-black cosmic space filled with swirling brushstrokes, tiny stars, faint nebulae, and exactly two large ringed planets: one planet in the upper left with blue rings and yellow-green land masses, and one bluish-purple ringed planet in the upper right. Traditional oil-on-canvas texture with visible thick impasto brushwork, dramatic soft highlights, rich blues and warm browns, and a whimsical retro sci-fi fantasy mood. No text or watermarks.
