One of the really bad things you can do to your writing is to dress up the vocabulary, looking for long words because you’re maybe a little bit ashamed of your short ones. This is like dressing up a household pet in evening clothes. The pet is embarrassed and the person who committed this act of premeditated cuteness should be even more embarrassed.

Good description is a learned skill, one of the prime reasons why you cannot succeed unless you read a lot and write a lot. It’s not just a question of how-to, you see; it’s also a question of how much to. Reading will help you answer how much, and only reams of writing will help you with the how. You can only learn by doing.
