Sadly, the only real era of his work that I'm familiar with is the most recent Lord of the Rings and Star Wars movies. I've seen one, maybe two, of his Hammer films, but not as many as I should have. Either way, the guy was pretty cool and had a voice I won't easily forget.
The whole thing was done in Manga Studio. Tried using some of the watercolor brushes for the rendering. pretty happy with how they worked.
