For some reason , when I draw a character, I seem to start with their legs/trousers.
It's not what I would have thought would be the normal foundation for creating a character, but they do often come to me trousers first.
Then if I get the neck and nose right, I feel I'm on the way.
Then I think of a hairdo.
But I do tend to leave arms till last.
Sometimes I only stick arms on when I sketch them doing things.
Maybe it's a bit like Alec Guinness only feeling he can properly do a character when he's got the right shoes.
