I thought he brought a certain John Buscema like nobility to the Thunder God. It's one of my favorite commissions. A few years after I got this sketch, I got to meet Tuska at Heroes Con in Charlotte, NC. He was very pleasant although he could barely hear. He signed my copy of the excellent Art Of George Tuska book from Twomorrows which is an excellent overview of this great man's work.
It's a true loss for comic fans. At least we'll always have his excellent output through the years to remember him by.
