Go with Immortal..
the first thing I notice about a song is the title...calling this song Immortal grabbed my attention...then the first 30 seconds of a song usually tells me if I'll be interested in listening to the rest of it...the first 5 seconds had me interested...the rest of the song, in my opinion, is nicely balanced....as for the vocals that you need to add?...I'd suggest leaving it as is...too many songs i've heard where vocals ruined it...but I might be wrong...so just in case I'm going to download this song now and wait to see how the vocals turn out (if you add them of course)
Thanks! I appreciate the criticism. Yeah vocals are something that's going to be trial and error for many of my songs I'm sure, but I'll find some way to make them work whether they turn out to be harsh vocals or some other form. Glad you liked it!
Please contact me if you would like to use this in a project. We can discuss the details.
