Very nice arrangement of the song! It was very catchy! And that Video looked super professional!
Your pronunciation of the English lyrics were very easy to understand.
The only part I were I noticed your accent a bit more was when you would say "What are you (doing to me)?"
That didn't detract from the lyrics at all because I could still understand you, it was just your accent was a little thicker.
At the very beginning of the bridge (1:59- 2:11), I couldn't really make out the words you were saying but my confusion didn't last too long.
Overall I'd say you did a great job pronouncing the English words! Especially when you sung the "Where are you now?" part, it sounded like perfect English. There was only the one time I couldn't make out what you were saying.
