The background is softly blurred, focusing attention on the subject's face and attire. The painting is executed in oil on canvas, a common medium for portraiture during the Romantic period. Delaroche's technique showcases fine details in the fabric of Montfort's clothing, as well as the subtle play of light on his face. The dimensions are approximately 65 x 80 cm, making it a relatively intimate portrait.

The brushwork is smooth, contributing to the lifelike quality of the subject. Paul Delaroche was a prominent French painter known for his historical and portrait works.
