Some Acoustic Guitar Playing - need some feedback

[Plotark]

Hello everyone! So I started playing the guitar a exactly one year ago and I've been playing like a madman since. Fortunately I bought a mic a few weeks ago and I've recorded a little song. It's a cover of Free Fallin' by Tom Petty, played in the style of John Mayer and brutally influenced by this youtube video: http://www.youtube.com/watch?v=U4FOGkFjyLc

Anyhow, here is the song: http://soundcloud.com/elias-frost/free-f...stic-cover

I would really appreciate if you take a few minutes to listen and give some feedback on how I can improve my playing. Even though not many of you are musicians, I'm pretty sure I'll get some great advice from you. Thanks!

You're pretty good, definitely better than me but the tapping-your-hand-on-the-guitar thing, to make that kinda drum sounding, percussive effect drives me insane. Other than that it's fine :3
