Dearest underwhere,
The quandry as you view it comes down to a question of why you write. Do you write to tell a story (write for yourself essentially.) or do you write to be read. Probably most people do both to varying degrees. You have a story you want to tell and hope others will read and enjoy it. The second motive is a social act that requires your ability to manipulate the thoughts and feelings of your audience in a predictable way; you want them to think, feel, and react to your story in the way that you intended. That is where we run into common rules loosely based on social expectations.
OK listen up, The long, hard, and fast, but not too fast, rule is. You use descriptives of your character if and only if.
1) It is essential to the nature of the character(blind, peg legged, pirate)
or
2) the description advances the plot of the story.(blind, peg legged, ethnically diverse pirate with a soft spot for bleach-blond Hispanic transvestites)
Now you have a rule to violate, enjoy yourself.
