Ephel Duath - Crystalline Whirl tab

I was bored on a sick day so I figured out the first few parts.
You'll have to listen to the song for the rhythm.
I don't think this song in standard tuning but this is the way I figured
out how to play it so the fingering might be a little tricky.
If you can add to it/correct it/improve it in anyway let me know.
This is my first time tabbing something, I hope it's not too bad.
That should be about it. Enjoy.

If you can add to this that would be great. I'll try to add more when I can but the rest of the song I think is beyond my ability to tab.
