I'm so glad you managed to get a track in! This is very well mixed on the whole, and you're so talented with creating ambience. It'd be interesting to know your thought process behind each different part in this song. I don't actually think there's anything wrong with threading together different ideas in one song, but it'd be nice to know if there's a story behind each part. I think that would help guide the listener through a journey in your music!
There are many parts of this that I really love. Particularly the part that comes in around 2 minutes. That bassline is great and really goes well with the bells. Those voices that come in at 2:30 too are so atmospheric! The strings throughout are emotional and very well composed. I think the transition at 3 minutes could have been just a tad smoother!
The part at 3:58 was a really nice addition too. I think this track would go really well with a short film. The ending seemed perhaps a little abrupt, but nothing totally offputting.
Maybe you could go back to your description and put your thoughts on each part of your track? I think it would help make more sense of what you've intended and definitely work in your favour, when the judges come to look at your track especially ;)
All-in-all, I really enjoyed this. I've given it five stars because despite the little parts I suggested that I'd tweak, if I were rating this, it'd still be like a 9.6/10! I always enjoy your work a lot and you bring something special with each track that you do. Something that is unique to your work.
Also, I'd like to wish you a Happy Birthday! Keep doing what you're doing because it's fantastic.
