The best start in any drawing/painting/sculpting medium
is to have excellent reference material.
Always bring a sketch book along...
or a few napkins...
or a receipt...
or a ticket stub!
You hear me...you've done it before!
Take your own pictures...or draw to record.
Most images are protected under artist copyright.
It is important to respect those laws...
You can look at TONS of pictures for inspiration,
details you may have missed...background ideas.
But don't design your art from them.
1st~ Your perspective is unique to YOU.
Keeps the design fresh.
2nd~ Seeing the actual subject helps you capture
the neat little details you can't discover
from 1,000 images...sheen, texture...
sometimes SMELL! (Whooo-wee!)
3rd~ It's safe. If your design is selected for
production on cards, mugs, fabric etc.
You know it is your property!
Copyright infringements are serious.
