I try to keep it loose, so a lot of the real decisions happens in a sketching and inking mixture. So my page-breakdowns is very much about timing and dialogue. That means that they tend to look like something that is not even doodles - and my family in law are very tidy people that insist on helping out when visiting. It is they I suspect!
I am a perfectionist myself and I have come to view perfectionism as Marsellus Wallace view PRIDE.
