Your accent will always be your accent because guess what? All of us have an accent, people from New York sound different from the people from Alabama. I have a very strong accent from Colombia and that’s just how it is. As long as people understand what you are saying, do not care about your accent, that’s part of who you are. So be it. Plus you have a nice and smooth accent 😉

To my English ears, your accent sounds very lovely.

If your wanting to change your accent to sound more native my advice is choose an accent u want to immitate from that language (such as if you wanted to sound more British you could choose English,Scottish,Welsh etc or go even further with specific region or city in the country like a London accent) and learn prounounciation more in that accent and that should help you if your looking to sound native because you want to. That being said no need to be insecure about your accent your English is very coherent with your accent and 2 years practicing is showing too you have good pronounciation of the language like i said no need to be insecure about anything 🙂.
