In this vertical composition, Sleeth utilizes the quick-drying nature of acrylics to build a scene that feels both solid and ethereal. The work moves away from literal representation, favoring a structural abstraction that emphasizes the verticality of the riverbank and the deep shadows of nightfall. Broad strokes and subtle tonal shifts suggest the movement of water without defining its edges, allowing the viewer to settle into the atmospheric stillness of the dark.

The choice of a portrait orientation for a landscape subject creates an unusual sense of depth, drawing the eye upward through the gloom rather than across a wide horizon. By stripping away fine detail, Sleeth focuses on the emotional resonance of the 'nocturne'—the way light clings to the surface of the river just before it is swallowed by the night. It is a study of presence and absence, rendered with a hand that values the raw energy of the paint over precise imitation.
