Can anyone please correct my pronunciation or intonation mistakes?

Il mio paese, secondo me è il più meraviglioso di tutto il mondo nonostante la corruzione. Sono della Colombia, sono contento di esser nato qui, mi piace la gente che ci abita, siamo gente che lavora duramente (la frase successiva non ha soggetto??), vivo a Bogotá al nord della città, anche il cibo è buono, abbiamo biodiversità e bellezza naturale

If two shops are roughly the same size I would say they are opposite each other or facing each other. Across would not be my first choice for describing them. When you go from one to the other, you are walking across the aisle. In general, in the malls where I used to go before the pandemic, I would say that shops were on both sides of the aisle.

There are many people who want to learn a new language. Humans need to socialize with people who live in other countries. My father and my mother had French classes when they went to school. In my case, I've studied English since I was a child, although I really wanted to learn English, three years ago, when I started to study English at the language school. Anyway, learning a new language has some advantages and disadvantages.

On the one hand, if you start learning a new language, you are going to make a lot of friends. You need to practice your language, so you need to speak to anybody who want to practice with you. I can say, I have personal experience in this. I have a friend from France who live in Getafe, and he can speak English, French, and German. I have another friend who lives in Parla, and he can speak English because he lived in the USA, although he is from China. And my fiancée, she can speak English and French as well. That's very funny. Besides, you can improve your job. There are many jobs that look for workers who can speak other languages. They need to communicate in other languages with customers. In my poor English, I've had to communicate with Apple technicians in English by mail. So, I've chosen this language because it's important for my job.

On the other hand, learning a foreign language can be expensive, especially if you pay for private tutoring. There are some people who prefer hiring a tutor, so they can learn more quickly than other people who prefer reading books or computer programs. Moreover, learning a new language is a challenge. Many languages have a different  grammar, alphabet, and set of sounds. You need to be persistent, hard-working, have time and interest.

In conclusion, if you want to learn a new language you have to know that it isn't simple, but it can be funny.
