1. Medium: Watercolor on paper

2. Shapes and objects: A landscape featuring a body of water (likely a river or lake) in the foreground. There's a small sailboat with yellow sails on the water. On the far shore, there are buildings, including a white structure with arches that could be a boathouse or pavilion. Trees and vegetation line the shore. The sky is light blue with some clouds.

3. Colours: Blue dominates the water and sky. Yellow for the boat's sails. White and pale yellow for the buildings. Various shades of green for the vegetation. Soft browns and greens for the shoreline.

4. Narrative: This painting captures a serene waterside scene, possibly at a resort or vacation spot. The sailboat adds a sense of leisure and recreation to the scene. The arched structure on the shore suggests a well-developed area, perhaps a park or a private estate. The overall atmosphere is one of tranquility and pleasant outdoor activity. The composition invites the viewer to imagine themselves in this peaceful setting, perhaps enjoying a day by the water.

5. Original Artist: While this is an original work by Mehrdad Fahimi, the style and subject matter are reminiscent of the waterside scenes painted by Claude Monet, particularly his works at Argenteuil. Monet was known for his impressionistic depictions of light on water and his interest in capturing fleeting moments of everyday life.

However, Fahimi's use of watercolor and his more defined architectural elements also bring to mind some of the works of American artist John Singer Sargent, who was known for his watercolor landscapes and architectural studies.

A comparable work might be Monet's "Regatta at Argenteuil" (1872), though Fahimi's painting has its own unique elements and a more transparent watercolor technique. Monet's works can be found in major museums worldwide, including the Musée d'Orsay in Paris and the Metropolitan Museum of Art in New York.

While Fahimi's painting is clearly his own, it seems to blend influences from both Impressionism and more traditional watercolor techniques, creating a scene that feels both familiar and freshly interpreted. The painting continues the tradition of capturing the interplay of light, water, and architecture in a serene outdoor setting.
