In a post published April 26, 2015, I recommended A guide to understanding persuasive language, provided by the University of New South Wales, Australia. This guide provided excellent advice on developing writing and speaking skills.
Unfortunately, this link is no longer available, but don’t despair! I have found a well-written, concise guide on Literary Techniques by the BBC which focuses on how to use descriptive language techniques effectively. Click on the picture below for the link.
