Marvin's Teaching Approach
To paint well, one must learn to think well. As Michelangelo wisely stated, a man paints with his brain, not with his hand.
My teaching is rooted in the conviction that portrait painting is not merely a collection of techniques, but an organized way of seeing, understanding, and making decisions. Technique matters, but technique without understanding can only take an artist so far. A strong portrait depends upon the intelligent integration of many elements: drawing, structure, proportion, color, light, composition, materials, and process. My aim is to help students grasp the underlying logic that connects these elements, so that their work becomes not only more skillful, but more coherent, expressive, and alive.
Through real time demonstration, close analysis, and practical application, I guide students toward a fuller understanding of how a portrait is built and why each stage of the process matters. Although the course is taught through portraiture, the principles it addresses are not limited to portrait painting alone. The underlying logic of picture-making is universal, and what students learn here can be applied to any subject matter. Ultimately, my goal is to help each student become the strongest version of themselves as an artist by developing a way of working that is grounded not only in practice, but in understanding.
