Not much different from the real one
At some points the audio was a little fuzzy or scratchy, but I think that it's the fault of your programs, not you. Good job with the song. I could easily identify what you added, but it seemed like you mostly stuck to the original. If you redo this, make it more your own song! Change it more!
Please contact me if you would like to use this in a project. We can discuss the details.
