Tuning E A D G

I Finally tabbed this song...i hope its close to being right cause i can't
really hear the bass line in this song

Riff 1
G|---------5-3-------------------2--|
D|---3---------5-----3-----5--3-----|
A|6-----3---------6-----3-----------|
E|----------------------------------|

On second time that you play Riff 1, skip the last note and go to Riff2

Riff 2-a            Riff 2-b
G|------------8h---|-----------8h---|
D|6--6-6-6--6h--6--|8--8-8-8-8h--8--|
A|-----------------|----------------|
E|-----------------|----------------|

Play Riffs 2-a & 2-b a couple times, then on the last time after 2-a play:

Riff3
G|---7-----------|
D|8--------3-----|
A|------6-----3--|
E|---------------|

Now play Riff 1 On the last time hold the last 3 on D for quite a long time, and same for the A (2nd fret on G), then go to Riff 2.  
Follow the same basic pattern to Riff 3 and Riff 1.

Play Riff 4 to the end after a while of playing Riff1:

Riff4
G|---------5-4-2--|
D|---5--3---------|  
A|3---------------|
E|----------------|
            
Play Riff 5 until the songs end

Riff 5
G|---5--|
D|3-----|
A|------|
E|------|
