Good to see a good Beatles cover out there. The only flaw in your cover was the vocals when you sang the "so please, please, please, love me do" part. It seemed like you weren't properly carrying the note out - or you were carrying it too long. The piano sounded great and the whistling was neat too. I'm not trying to be harsh but I'll be honest; you have great talent, but next time try to make the vocals sound better.
I liked this enough to say this.......Keep working at it! Practice makes perfect.
