Then the level of detail falls away still more: while amateur writing is plagued with 'the blue-eyed girl' and 'the red-head', better authors will come up with epithets that are actually pertinent to the situation at hand and have some creativity about them, which is rarely generic physical description. (There's also a lot less use of epithets in general, I think, probably because the scenes and sentences are more skilfully constructed so that identifiers aren't as necessary, and the prose or dialogue can flow on without them).
Film adaptations of books don't usually cause casting controversy because there's a perfect description of the character which is ready-to-hand - quite the opposite. Fans have put together differing mental pictures from relatively sparse detail, which then must inevitably clash with whoever's been chosen for the part because you can't satisfy all the separate ideas.
As a very general rule - and I say this as someone whose personal taste in literature is for richer description, not stark elegance - it's usually better to aim for sparse prose. There's the basic benefit of paring your writing down to exactly what it needs to say, without hiding any of the important parts beneath excessive verbiage, which is something all teachers and editors will encourage you to do. Then, even if your actual language use isn't the most brilliant work of genius, you can still carry readers along by raw virtue of everything else it conveys, whether that's the story, the concepts you're exploring, or whatever. It's just an unobtrusive medium for you. But excessively florid prose is an immediate negative, and actively hinders the audience from getting to what else might be good about your work.
