Here are some suggestions for improving the natural flow and grammar of your sentences: 1. Original:
Yea, I also saw these reels😁 I think it shows that everyone can learn English and it’s accents if dedicate enough time and effort ☺️ This girl is a real example. I don’t know her background but I want to believe that we can learn English as well like she did 😁
 Improved Version:
Yeah, I also saw these reels!😁 I think they show that anyone can learn English and its accents if they dedicate enough time and effort.☺️ This girl is a great example. I don’t know her background, but I want to believe that we can learn English just like she did.😁
 Explanation of changes: * Changed "Yea" to "Yeah" for more common usage. * Adjusted "it’s" to "its" because "its" is the possessive form. * Added a subject, "they", in "if dedicate enough time" to make the sentence grammatically complete. * Replaced "real example" with "great example" for a smoother and more natural expression. * Simplified "as well like she did" to "just like she did" for conciseness. 2. Original:
When you get to know her/him you will be disappointed.
Improved Version:
When you get to know them, you might be disappointed.
Explanation of changes: * Replaced "her/him" with "them" for a gender-neutral and smoother phrasing. * Used "might" instead of "will" to soften the tone and make it sound less harsh or definitive. Let me know if you want further tweaks! 😊

I think it shows that everyone can learn English and its accents if they dedicate…

I would say 'I think it shows that everyone can learn English with a good/natural accent if they dedicate enough time and effort' :) Also 'We can learn English as well as she did'! Other than that, really good job 👍👍

… as well as she did.

#2 is correct
