Creative Rationale

Over the high Andes of southern Peru or northern Bolivia, this location sits at extreme altitude where the atmosphere thins dramatically, explaining the unusually low sea-level pressure reading. The moderate temperature anomaly and dry conditions suggest clear mountain air with gentle winds flowing down from glaciated peaks. These atmospheric conditions inspire a composition of luminous, breathing clusters against an open ground - the low pressure creates expansive luminous passages while the dry air and calm winds form rounded, blooming gestural marks rather than dense overlapping strokes.
