Some more inspirational material, although less wild west and more Victorian era: Dinotopia. The book details a shipwrecked crew who find a lost island where humans and dinosaurs co-exist. It looks like some terrific art. I figure I might get the 20th anniversary edition when it’s released in September.
Not much else to say about that, but I did add it to the “recommended reading” section. Now to just resist the temptation to add airships (that is always, always a temptation).
