What Do You Think?

I made this cover.



It's supossed to be a cover from the Beatles, but I got it from the movie, Across the Universe.
I want to know if it's good. So far, my girlfriend likes it, and my other two friends both like it. Once of them flipped and was like "WOW", so I don't really know. But other friend Matt, he was like "I think I need to give you singing lessons." which i totally agree with. I don't think I'm a good singer.

But either way, they're my friends, and they were being nice. Matt was the only one with constructive critisism. So could you give me some of that, please?

Also, I need some recomendations for songs. So far I've gotten some requests for Green Day and Bright Eyes, but I need some more.

thanks =]
