Again a great piece. I find it quite hard to critique you Step. You make amazing pieces, and most of my points come from my personal opinion, in which it is very hard to find anything that I dislike in your song. However there is one thing that I definitely noticed. You don't make loops very often do you?
When you export your song as an MP3 there should be an option to wrap the ending which "Should" take your lasting effects at the end of the piece and wrap it into the beginning of the piece. I use this for loops all the time, and in this piece, I feel it is quite necessary so you don't get that distinct cut off. Either way, I think you should play with that ending bit just a bit and see if you can't get it to play out that way, as that would make a huge difference in the quality of the loop!
Overall this is a fantastic piece and I am not going to let that looping bit muddy your score. 5 out of 5 Step. You deserve it as this is a great piece of music!
