Mainly - you need to work on some more melodies - this one is long and repetitive. Also the piece lacks some powerful energy - maybe u should add this in Ambient.
You're right, it is unfinished stuff to be honest, should have finished it first. The next thing on the agenda was to shorten the first half to 2 repeats of the verse or find something to fill the second 2 repeats of the verse before the 3 minute mark before you mentioned it. I think the energy depends on how loudly you play it, cheers for your feedback! x
