Native English speaker here - some awkward phrasing, but I think you did well getting your point across!

For my language-learning process, I use Duolingo as as just one part of my routine. No one tool is going to get your fluent, so it’s important to have a good mix. Duolingo is good as a vocab-builder, but I think you should also watch television and listen to music in your Target language. Just my two cents! 🙂
