I think the verse riff might be alternate picked rather than down picked on the low B string. I figured out this song by ear as well awhile back, I may be wrong. Good job though! Ebony Tears is unfortunately forgotten in lists of great Melodic Death Metal bands from Sweden
I think it's all down picking. However, I couldn't do it, so I played some parts using alternate picking... I think "Harvester of Pain" is the best melodic death song!
