1. Medium: Watercolor on paper

2. Shapes and objects: This painting consists of two separate landscape sketches side by side. 

Left sketch:

- Mountains or hills in the background

- Trees and vegetation in the middle ground

- Large, round shapes in the foreground, possibly rocks or boulders

Right sketch:

- A forest scene with various trees

- A wooden fence in the foreground

- Blue sky with clouds

3. Colours: 

Left sketch: Greens and yellows for vegetation, browns for the rocks/boulders, light blue for the sky

Right sketch: Various shades of green for the trees, brown for the fence, blue for the sky

4. Narrative: These sketches appear to be quick studies of different natural scenes, possibly done on location. The left sketch captures a more rugged, mountainous landscape, while the right one depicts a more pastoral scene with a managed element (the fence). Together, they showcase different aspects of natural landscapes, from wild to more cultivated. The loose, quick style suggests these might be preparatory sketches or studies for larger works, or simply quick captures of observed scenes.

5. Original Artist: While these are original works by Mehrdad Fahimi, the style of quick, loose landscape sketches brings to mind the field studies of several artists:

- John Constable, the English Romantic painter, was known for his quick oil sketches of landscapes which he would later use for larger paintings.

- The Group of Seven, Canadian landscape painters, often made quick sketches en plein air before creating larger studio works.

- Contemporary artist David Hockney has produced numerous landscape sketches, particularly of the Yorkshire countryside.

Fahimi's approach here seems to blend traditional landscape sketching techniques with a more modern, simplified style. The use of watercolor for quick studies is reminiscent of the practice of many traveling artists and illustrators.

These sketches continue the long tradition of artists using quick studies to capture the essence of a landscape, serving either as memory aids for later works or as complete pieces in their own right, valued for their spontaneity and directness.
