several spray-painted artworks displayed on a textured stone ground, likely a sidewalk, in Saint Petersburg, Russia. The art pieces feature stylized landscapes with prominent celestial bodies like moons and planets, often with silhouettes of figures or objects. One painting depicts a bright green moon with silhouetted figures and structures. Another features a red moon rising over mountains with a lone samurai figure. A third artwork shows a pink and blue swirling sky with a person on a surfboard riding a waterfall. There is also a black and white painting of a large moon casting shadows over a landscape. In the foreground, two phone cases with abstract, colorful designs are placed. In the background, a blue and white plastic bag with Russian text and some spray paint cans are visible, suggesting the artist's setup. The overall scene suggests an outdoor art display or market.
