The intro was interesting and kept me going simply because I wanted to hear what would come. At first I thought that it wasn't really going anywhere and when it did drop down it threw me off for a moment and I wasn't sure what I was hearing. Slightly past the one minute mark you simply repeat the same set over and over while leading into a more complex them based around...well...I am not completely sure what that instrument is. Anywho, middling out I find that you bring in a more calming feel and a basic area which leads into more repeating. Thing is the repetition in this song isn't bad, it keeps you going but frankly I started getting bored just after the middle of the track as it felt like it slid back into an area that was already visited and all the sites were seen already. I can really see this turning from an Ambient track into something with more of a epic classical feel or simply a classical feel period. Not bad, not bad at all.
Oh, and the ending to this piece is horribly lacking. It shuts down far too fast. Might I suggest something like placing the reverbed piano/thingy that was used in the beginning in the end and letting it fade/echo away. It would really help.
Thanks for your comment, I will do more variation in my song.
