Interior Mass explores the idea that form accumulates from within rather than appearing at the surface. A dense, organic shape emerges from a deep blue field, shaped by pressure, repetition, and time. Its porous edges suggest growth and erosion rather than fixed boundaries. Built through scraped, dragged, and layered gestures, the surface carries a geological weight and internal motion. The surrounding blue actively contains and shapes the form, creating tension between expansion and restraint. At a 3 × 3 ft scale, the painting rewards close viewing, revealing how meaning gathers slowly through sustained attention rather than immediate recognition.
