Final answer:
Cedric should enroll in an oil painting class to learn techniques used by artists like Monet, van Gogh, and da Vinci.
Classes focusing on Impressionism and painting en plein air are recommended, as well as a general fine arts program that covers a variety of painting techniques.
Step-by-step explanation:
To best support Cedric's goal of creating artwork in the same medium as artists like Monet, van Gogh, and da Vinci, he should look for an oil painting class.
This type of class will teach him the classical techniques used by these masters, as well as how to work with the textures and colors essential to their styles. Da Vinci's work, such as the Mona Lisa, is known for its use of Sfumato, a technique he could learn in an advanced painting class.
Claude Monet's use of intense pure color is characteristic of Impressionism, which can be explored through classes that focus on this era and its painting techniques. Additionally, learning about the practice of painting en plein air, an approach common amongst the Impressionists, would be beneficial.
For a comprehensive education, Cedric might consider enrolling in a general fine arts program that covers a broad range of techniques including those used by Cézanne, such as layering paint in thick layers to build up form and color, and Toulouse-Lautrec's use of large, loose brushstrokes.
