Descending Chaos - Haunted Souls (A little help to move forward)

Where else would I turn for opinions than the forum hear? I would prefer brutal honesty for what I'm about to ask. I do the vocals and write the lyrics for A Gothenburg, Sweden death metal -band called Descending Chaos. I would like to ask if there is something we could do better or improve. We are currently working on the last arrangement for our EP. We do it all ourselves this time so before we to the finishing touches I would just like to hear your opinions about it.

And yes, we're on Spotify, iTunes, YouTube etc
