I edited it from your suggestions is there anything else I could change or add?

The smell of exhaust from multiple cars combined with dirt and dust fluttering in the air is my lasting impression of Canton, China. The vivid image frequently reminds me of where my origins came from and how far I have come. The American dream means a tremendous amount to many who dream of enduring a long yet rewarding voyage to the land where dreams come true. For that reason my parents immigrated to America to pursue greater opportunities, that isn’t offered anywhere else.

Traveling in the afternoon in our red Honda Accord, I was gazing at the trees whizzing by transforming into a blur, as we tried to reach our destination in Virginia. My mother began talking of a moment she had once experienced while the radio was turned down to a whisper. She became motivated to convey to my brother and me the importance of an education. My mother spoke about how she and my father have worked many difficult and arduous hours in order to assure a better lifestyle for my brother and me, while reiterating the importance aspects of her speech to be sure that we heard her. She began to illustrate the purpose behind this lecture. I finally realized at age eleven that my mother was declined an opportunity for a high school education because of her age when she arrived in Denver, Colorado, which is where my mother resided after arriving in America. She was devastated that she couldn’t go to school like the rest of her siblings, as they went off to a school were they would learn English. Since her youth in Colorado my mother has learned to comprehend and speak English. I am satisfied that she was able to overcome a major disadvantage.

From that moment on I have an extra incentive to challenge myself and realize the importance of an adequate education. I am obligated from my conscience to succeed and make my parents proud of my accomplishments. There is nothing more joyous than seeing the ones who raised you realize that their hard work has paid off. It has become my duty to bring them joy, especially through their hardship of assuring that my brother and I have a better childhood than the ones they experienced. My inspiration comes from my mother who has provided me with motivation that I would never experience if the epiphany in the car on a late afternoon didn’t occur.

The changes you made to the paragraph are great! However, there are a few more suggestions to improve the coherence and flow of the paragraph:

1. Instead of repeating the word "dream" in the sentence "The American dream means a tremendous amount to many who dream of enduring a long yet rewarding voyage to the land where dreams come true," you can rephrase it to "The American dream holds immense value for those who strive for a challenging yet fulfilling journey to the land of endless opportunities."

2. In the sentence "For that reason my parents immigrated to America to pursue greater opportunities, that isn't offered anywhere else," you can rephrase it to "That is why my parents decided to immigrate to America, in search of unparalleled opportunities not found elsewhere."

3. Instead of saying "My mother spoke about how she and my father have worked many difficult and arduous hours," you can change it to "My mother spoke about the countless hours of hard work and sacrifice that she and my father dedicated to ensure a better life for my brother and me."

4. In the sentence "I finally realized at age eleven that my mother was declined an opportunity for a high school education because of her age when she arrived in Denver, Colorado, which is where my mother resided after arriving in America," you can rephrase it to "It was only when I turned eleven that I discovered my mother was denied the opportunity for a high school education due to her age when she arrived in Denver, Colorado, where she first settled in America."

5. Instead of saying "She was devastated that she couldn't go to school like the rest of her siblings," you can rephrase it to "She felt immense disappointment that she couldn't attend school like her siblings did."

6. In the sentence "I am satisfied that she was able to overcome a major disadvantage," you can rephrase it to "I am convinced that she managed to overcome a significant disadvantage."

By incorporating these suggestions, you will further enhance the clarity and coherence of your paragraph. Great job on your revisions so far!
