When we're writing using the senses is important and the one used the most is sight. Words chosen to show a reader how to visualize the characters and the setting are used. If your reader can's visualize these things, they're nto going to continue reading.
Often, in a rough draft right we might write something like she saw him. Now this is such a pedestrian use of sight that when reworking the scene. You might write something like this. He entered the room. She wanted to run to him and throw her arms around him. Now this brings a bit of difference to the scene. Or you could write. Her gut tightened when the tall, dark haired man strode into the room. She wanted to knock him down a peg from his arrogant posture. This tells you something more and the sight of him becomes more visid.
The same goes for setting. The gardens were lovely. Now this is not only boring but passive. The glorious rose bushes bloomed in brightness. Shades of red from pink to a deep maroon lined the flagstone walk. Just beyond there were bushes of witte and yellow. Her favorites were the ones in shades of lavender. Now this gives a picture of the garden and its loveliness.
So when you're revising take the time to show your reader what they're seeing and you'll find they'll want to read on.
