This is the one thing that drives me insane more than anything else about drawing. The pictures in your head move so fast. For me its especially when I listen to music. But then......the fucking pencil moves SO slow.
How would you cope ?
I try to meditate before i draw to clear my head.
Other things that sort of speed up the process:
-drawing gesture lines first
-drawing forms with a large brush
-looking at the overall picture
Those things sort of help.
