Can someone think of something to complement this?

I can't figure out anything to go with these parts.

x = palm mute



e|--------------------------------|
B|--------------------------------|
G|--------------------1-------4---|
D|0-2-0-2-3-0-2-3-0-3-----0-3-----|
A|--------------------------------|
D|--------------------------------|(x2)

e|--------------------------------|
B|--------------------------------|
G|--------------------------------|
D|2-0-2-0-3-0-3-0-2-0-2-0-3-0-3-0-|
A|2-0-2-0-3-0-3-0-2-0-2-0-3-0-3-0-|
D|2-0-2-0-3-0-3-0-2-0-2-0-3-0-3-0-|(x4)
x x x x x x x x x x

and then, at some point in the song:


e|--------------------------------|
B|--------------------------------|
G|--------------------------------|
D|0-2-0-2-3-0-2-3-0-3/6===0-3/9===|
A|0-2-0-2-3-0-2-3-0-3/6===0-3/9===|
D|0-2-0-2-3-0-2-3-0-3/6===0-3/9===|(x2)

very difficult to attempt without hearing the riff w/ real rhythms (or at least writing them out). try to make a scratch of it.
