Creative Rationale

Over the inland Pacific Northwest of Washington State, near the Cascade Range, extremely cold arctic air masses collide with moderate winds under low pressure conditions. The bitter -45°F temperature anomaly and dry 23% humidity create a landscape of crystalline clarity, while the 13 mph northeast winds drive scattered bursts of muted color toward the canvas edges. I've interpreted this harsh winter scene through Francis's gestural language - sparse, earth-toned splatters flung outward by wind energy, with heavy color pools accumulating at the borders under low pressure, leaving vast expanses of luminous white space to represent the stark, breathable coldness of this high-altitude winter atmosphere.
