Descriptive writing flows from your understanding of what you want to say and you use your own vocabulary and styles (we call that your voice). It's not what someone called "that flowery stuff that embellishes stories."
For example, why would you write "her visage" or "his countenance" when you'd normally use the word face?
Descriptive writing tries to create an image—a picture—by selecting exactly the right words that clarify. You provide visual details that include sounds and smells, and texture.
Here's my favorite explanation, written by Richard Price: You don’t write about the horrors of war. No. You write about a kid’s burnt socks lying in the road.
You need to present the most significant details—those that reveal the essence of the person, object, action, or situation.
To write descriptively, I don't need to search for strong verbs;
I need to embrace my own natural voice.
