Feed The Fire Intro Tab

I wanted to build upon the chords tab already submitted and add some color so riff itself so other people can
pick it up.
 
This is my first tab ever, so pls go easy on me - I'm 90% certain this is correct.
 
The riff is in D Dorian. The chords used are Dm7, C and G. The voicings are as follows:
 
Dm7 C G
e------------|
B--6--5--3---|
G--5--5--4---|
D--7--5--5---|
A-/5--7--5---|
E------------|
 
The turnaround is based on an open position D power chord.
 
e---------|
B----3----|
G-0h2-2p0-|
D-0-------|
A---------|
E---------|
 
Putting the whole thing together looks like this:
 
       Dm7    C    G    Dm7
e--------------------------------|--------------------------------|----
B---------6----5----3-------3----|---------6----5----3-------3----|----
G---------5----5----4---0h2--2p0-|---------5----5----4---0h2--2~--|----(repeat)
D---------7----5----5---0--------|---------7----5----5---0--------|----
A--(2)/5-(5)---7----5------------|--(2)/5-(5)---7----5------------|-(2)
E--------------------------------|--------------------------------|----
 
A small variation of this riff repeats throughout the entire song. Listen close to subtle differences, like
ending the riff by letting the G ring out.
