The Same Subject at Three Grid Sizes

16 columns10.69 mm cellsCenter reduced to a two-cell blob; the leaf is two cells and reads as noise.
32 columns5.34 mm cellsCenter holds at four cells across. Comfortable to color.
64 columns2.67 mm cellsEvery detail survives — and there are 4,096 cells to fill.
