Space (Wind)

Drawing clothing, angelic robes or other sort of
shawl or scarf, or long hair sweeping in a wide
arc around a central figure allows you to suggest
space (wind). Special effect lines representing
wind appear in 2 locations at the top and bottom
of the composition.
Tipse wind lines, not visible in actuality, are used to create a sense of the ,,air,s
density" or speed. The lines can be rendered in various forms, be it straight or
curved. Here, sweeping arcs are used to suggest air swirling. Having the wind
lanes become finer as they wrap around toward the back of the figure allows the
lines themselves to give the composition a sense of depth.
