More Creative Writing

My creative writing is a major work in progress. Let's just say I have a lot to learn. For one thing, comma splices? Apparently they are a major thing, whoops!
So I figured I would share another small piece. This one had to focus strictly on the sense of hearing.
What do you think?

All around her people whizzed by hooting and hollering. The young girl just stood, and stared at the big machines as they went whoosh around and around, screeched and shrieked their rusty way up the hills, and creaked and groaned their way around the enormous circles. When the girl turned her head to the right, she heard the jolly laughter of children and little feet padding the ground. Mothers and Fathers gayly and vigorously encouraging their children to “wave!” and “smile!” She also heard bouncy music booming from the speakers all around. When the girl moved her head to the left, the noises were quiet different. On this side they were not charming and pleasant to the ear. Instead, the noises were a mixture of many sounds that needed to be deciphered. To start, the ground rumbled and shook from both the machines and the big men and women that ran so fast they left a booming thump-thump-thump. Their voices were a mixture of enthusiastically squealing in delight and glee to appalling sounds of grown men and women moaning and blubbering. One thing for sure, every voice was largely animated.
When the girl walked closer to the largest contraption, she could faintly hear sounds of people gagging as they hollered, “I am never doing this again!” The sounds wafting from the children’s side seem so much more subdued, but the girl wondered why so many more people chose to scream, yell, and complain by the biggest machines. The young girl had to try it for herself as she took her place in line for the noisiest roller coaster, the one where the earsplitting sounds reverberated from. After all, the noises, shock, and fear are what an amusement park is all about.
