There are some parts of the intro where the notes are kind of tricky when it comes to 
timing them sequentially.
Perhaps I can't represent the note durations and pauses of the composition with such a note table.
...But I'm sure you can figure it out by ear and by practicing. The notes are as they stand.
Advice:
 Apply staccato in the initial notes. This way the listener hears the first key note of the upcoming riff,
 preparing them for what the near future holds.
 Put a bit of vibrato at the end of notes because it will emphasize them, which will add a dramatic effect.
 And in between, use legato so the melody flows buttery smooth through space. :)
