You could be playing the part wrong and that's why it sounds empty to your ears.
This is the chorus, sounds perfect with the master track...the X's aren't all ghost notes I just didn't want to tab everything out. It's easy to get the "strum" feel though.

Other things to try:
The easiest way to get each note to sound exactly the same is to use both your index and middle finger to pluck at the same time. Use the index for the high note and then the middle for the low note
Or, the way I play it, roll your finger over the top of the top note and then make the next string or the body of the bass or pickup that is past the low note the target.
