This is my first tab, but it sounds very accurate to me. Directly below is the main 
chords and the melody. However, there are a couple of possible corrections to the chords at 
the bottom if you think these ones are wrong. Try each out and use whichever 
sounds better to you :)

The melody sounds exactly right to me, however the chords may be slightly off, although 
they are definitely very close. The 'C' chord may be a 'Cadd9' chord, and the 'D' chord 
may be a 'D4' chord.
