Neither Anderson nor Pratchett describe anyone except if someone is very fat or thin, or very tall or short. Then they say that the person in question is is very fat or thin, or very tall or short. That's it. When someone is dressed expensively they just say he/she's dressed expensively. If their clothes are in tatters, they say the clothes are in tatters. No details whatsoever. None. Rincewind enters an inn. And that's all. Inside are a few people. Enough about that. A spaceship enters orbit. It's big and military. And that is all the description we get.
Now, I've tried to see how they bluff the reader into not noticing the utter lack of descriptions. Pratchett is obvious - it's the humor. A humorous one-liner characterization of a person, place, weapon, situation, city or town makes us laugh and we forget that we were in fact shown nothing. We were just enouraged to 'feel' through humor what goes on and put our own details into the situation.
J Anderson is humorless. He fills everything with endless recounting of who did what, thought what, felt what, but without an atom of actual description of the external world.
Compared to both guys James Patterson is Charles Dickens description-wise,and he's not known for being a description fanatic. He is today's minimalist Spillane incarnation.
And yet both Pratchett and Anderson are accepted as serious representatives of their genres, are respected, and widely read.
Lesson: a lack of description is totally irrelevant to what you write, as long as you have something else up your sleeve to compensate
Anyone agree or disagree?
