In writing I try to pare down the descriptive bits. If I feel that I could say something in as few words as possible, then I would rather do it than to go on padding. One should describe sufficiently to give the reader a sense of what one feels, but not at the same time overwhelm the reader in any way. For example, I feel that if you use lots of adjectives they have a mutually cancelling effect. If you can describe a scene well enough, without having to use far too many words, I would rather do so.
