Not that saying much would lend any kind of credence to begin with.
To say he had an impact on modern art, design and fictional enterprise is a vast and unyielding understatement. I got his autograph some years back on a pic of Big Chap along with Scott, Weaver, Skerritt, Kotto and Karl Toop, and it's unsettling and odd looking at it now as a piece of the past instead of the present.
He was an absolutely monstrous influence on my life and work, probably even still in ways I haven't encapsulated yet or learned to express. Few people are willing to approach things with the kind of honesty and lack of pretense laden adornment that he did, to speak their mind plainly and let their work speak on its own, for its own.
Fewer people still can claim to have created something 100% their own. He did all that and more.
The world is a smaller and lesser place today than it was before.
