4.5 out of 5.
This song captures the feel and atmosphere of aliens and the like. I like your choice of sounds in this. Well done.
The reason I gave this a Review Score of 4.5 and not 5 is because I feel the ending is too abrupt, and a remake of this that loops well would get a Review Score of 5 from me, or one that doesn't loop, but fades out nicely at the end.
I'm not sure whether this is Trance or not. It seems a bit more Ambient to me.
You did a good job on this. I hope to see more audio from you in the future! :-)
