Corrigan utilizes a squared composition to center her subject, focusing on feline anatomy as it adapts to the demands of a musical instrument. The illustration leans into a sense of whimsical playfulness, using the 'Harmonicat' concept to drive the visual narrative. There is a deliberate focus on feline expressiveness, where the cat’s posture and the placement of its paws suggest a genuine immersion in the music performance, bridging the gap between domestic pet and blues musician.

The work employs ink sketching techniques paired with bold color blocking to create a high-contrast, graphic feel that remains approachable. Brushstroke techniques are visible but controlled, emphasizing the texture of the fur against the metallic sheen of the harmonica. By exploring the intersection of animal behavior and abstract concepts of rhythm, the piece achieves a balance of technical illustrative skill and genuine wit.
