Creative Rationale

Over the high Altiplano of Bolivia and Peru, where the thin mountain air creates dramatically low atmospheric pressure, a gentle northwest wind carries sparse moisture across the stark landscape. The extremely cold temperature anomaly and moderate humidity suggest a scene of crystalline clarity punctuated by delicate atmospheric veils. These conditions inspire a composition of sparse, drifting calligraphic marks in cool blues and stark whites against a deep indigo ground, with the gentle wind creating horizontal processions of mark-clusters that fade and coalesce like breath in frigid air.
