Enjoyed hearing this, as for the vocals, I'm no singer, but I am like you are, that is someone who adds vocals to show how the song goes, you can't always do it with adding a melody with keyboards/guitar and stuff, you've gotta add some vocals to show how the song goes.
Bob Dylan couldn't sing to save his life, anybody who says Bob Dylan was a great singer has no clue what singing is all about. Bob Dylan was a great poet speaker in my opinion.
My point : Don't be afraid to try, and anyone who tells you otherwise is NOT A FRIEND OF YOURS!
Really enjoyed hearing your music, very poetic and interesting. I'm no Mix expert but the mix sounded good to my ears.
Keep on keepin' on!!!!
