It was just my personal opinion. If it offended you, I feel sorry.
Of course, you can and you should create your own rendering when you cover a classical song. But, unfortunately, you used exactly the same music as Faye did. So, your version is not really a cover, but a karaoke song. Faye changed the music to fit her voice and style when she covered Teresa Teng's classicals. I suggest that you check out Elton John's 'Sacrifice' and Sinead O'Connor's cover on Youtube. Now, both become classical.
