Look at some very amazing human face illustrations made exclusively in Flash.
Now who says that Flash is only for web applications and not for artists ?
Juniat says ..
Vector graphics let you work with lines and forms instead of a map of pixels, giving you amazing versatility and scalability.
Your drawings look good at any size and they weight much less than raster images.
I mainly start with a huge idea that I sketch on paper. Then I acquire it with my scanner and I begin tracing out the main outlines of the figure using only and exclusively Macromedia Flash.
After doing that, I start using the linear and radial gradients of Flash to give a first idea of 3dimensionality, that I complete adding more details with different shades and particulars like hair, eyelashes, eyebrows etc.
The final result is formed by a number of layers which changes according to the complexity of the illustration.
