A Day at the Ballpark- How to Write Descriptively

The writing technique of description carries immense power. The difference between great writing and mediocre writing is the ability to describe. Right below I have a very good example of some creative, and descriptive writing:

"I sat behind home plate, observing an unfamiliar name on the JumboTron. The rookie’s first at bat, read the screen. As he started to saunter up to the plate, I noticed an exiguous amount of sweat that lightly rested on his forehead. His eyes were full of drive and focus; never abandoned his trance upon the pitcher. If one listened ever so closely, one could hear his meditative breathing, inhaling through his nose and exhaling through his mouth. His tongue was like a frog’s, snatching the drops of sweat off his immature moustache like a frog snatches flies out of the air. One could just see the slight palpitations of the batter’s heart beat against his chest. His fingers were little snakes on the bat, nerves getting the best of him as his confident demeanor seemed to vanish. When he reached the batter’s box, he launched his hand directly in the umpire’s line of sight asking the umpire for time, like a crossing guard telling the oncoming traffic to stop. As he settled in the batter’s box his back foot imitated a drummer’s foot, bouncing up and down, up and down, in a slow, rhythmic pattern. As the pitcher reared back and discharged the ball toward the batter, he leaned back on his hind leg, cocked the bat, and shifted all his power and energy to move the bat forward to connect with the ball."

This is a prime example (maybe a little exaggerated) of how to dedicate a whole paragraph to a thorough description of a scene and character.
