I don't write songs, but I'm an avid lyric listener. And I love magical tales told in song (Peter Gabriel was the master of this for me, though Bowie was a genius too) which simultaniously call upon both the personal and the mythic - and all the ambiguous spaces inbetween.

I rather liked the neatly interwoven Cerberus related imagery in the song in the OP. It comes over as a Rock track, kinda Guns & Roses or something..
Some of the other songs felt a bit too loose and disconnected for me and I'd prefer them if the themes, images & references were tightened up somewhat, but that's a personal response.

I'd also second mg's assessement. IMO Cromdubh doesn't really need more advice than that offered by Alaska Mike.
