Marvin's Teaching Approach
To paint well, one must learn to think well. As Michelangelo observed, a man paints with his brain, not with his hand.
Marvin considers himself a lazy perfectionist. As Carolus-Duran, Sargent’s teacher, stated, “Achieve the maximum by means of the minimum.” A skeptic by nature, Marvin has explored virtually every imaginable path in search of what is most effective. He questions conventional thinking, accepts no rhetoric on faith, and is always looking for a more efficient and productive way to achieve the strongest possible result. This applies not only to his own work, but especially to his teaching.
His teaching is rooted in the conviction that 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 take an artist only so far. His aim is to help students grasp the underlying logic that connects drawing, structure, proportion, color, light, composition, materials, process, and strategic thinking, so that their work becomes not only more skillful, but more coherent, expressive, and alive.
Through real-time demonstration, close analysis, and practical application, he guides students toward a fuller understanding of how a painting 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 far beyond portraiture itself.
