The visual impact of Halley’s work is huge, immediate and explosive. This is partly due to his use of scale, color and sharp outline. Halley creates compositions that use Day - Glo and acrylic paints and areas of stucco texture to create subtle or brilliant effects. Despite his clear roots in Pop Art and Minimalism, the artist refers to his own practice as an intuitive project that gives way to a separate living space for his imagination. The notion of geometry as a social metaphor has served as the starting point for Halley’s entire artistic practice to this day. Halley’s iconography reflects his predilection for the element of the rectangular cell. Conduits connect the isolated cells to each other. Overall, Halley’s work presents a contemporary metaphor of urban existence. In this way, the artist’s entire oeuvre becomes the bearer of a deeper social message; the representation of a social landscape that reflects connectivity in terms of isolation.

After having explored in his last series the combination of canvases with drawings and digital wall diagrams, Halley returns strictly to the painting practice. Halley’s understanding of formal analysis is suggested in his control over the elements of art and principles of design. Within this context, the artist chooses to exploit the different effects created from varying the proportions, superposition or combination of his prisons and monochromatic panels.
