Writers, when using description, often forget that the purpose is to create a mental picture for the reader and not to have words overwhelm that function. Often words overwhelm this function as the writer uses it to show their love of words for their own sake.
Some writers use description to show their erudition, their knowledge of words, their vocabulary, and ability. When words intrude upon this function, then they tend to decorate rather than illuminate. Thus a writer must be ever vigilant that one does not befuddle the reader with an obtuse choice of words. The old adage, Keep It Simple Stupid, is worthwhile to consider. All the best writers adhere to that rule so their descriptions are clear, exact, and effective.
