Alma Real would be a good first track. Cut Muemerry in half & definitely add vocals, crazy shifting vocals, cos it's heading back to that redundancy. Haunted is good as is, don't redo vocals or have someone else do vocals. If you want to add female vocals just add some harmonies or flourishes--or just have her come in around 3:10-ish. Write two more songs w/ similar lyrics & this could be an EP worth giving a full review.
