Creative rationale

Over the high Andes of southern Peru or northern Bolivia, this location sits at extreme altitude where the thin atmosphere creates unusually low pressure of 623.7 hPa and cold temperatures of 5.2°C despite the tropical latitude. The gentle wind from the northwest at 1.6 m/s and moderate humidity of 70% suggest sparse, delicately drifting calligraphic marks flowing diagonally across a deep atmospheric field. I'll interpret this rarefied mountain air through Lewis's gestural language with sparse white and silver marks floating across a deep blue-black ground, their gentle northwest drift creating an airy, contemplative procession against the vast altitude.
