A good descriptive piece of writing needs many things to be good. First, it should include the 5 senses where appropriate. Second, it should have striking language. Meaning the use of good, rich describing words and figurative language. Third, it should provide a vivid mental image to the reader.
Now that we have had the chance to write a few different descriptive paragraphs I would like to write one on a simple subject. A Dragon!
Describe what it looks like, sounds like, smells like, feels like etc. Bring it to life in my minds eye. Include where it is and what it is doing.
