Cool...
I like it a lot. You have a nice balance with all the instruments. Very nice job mixing overall. And the melody lines are really interesting.
I like the choice of flute as for the melody lines. It has a very nice sound to it overall, and really creates a nice point of focus for the song. You might think about changing it to an oboe in one or two sections for a dramatic effect. Just an idea.
I like the harmonies created with the strings. You did well to create a nice and warm atmosphere with them. I personally think you could put some larger reverb on the strings. Maybe make them sound like they are in a cathedral or something. It might work, might not. Just a thought.
The one thing I don't like is the drums. It sound like you used a typical drum kit from a rock band. The exception being the concert bass drum you are using. It sounds good. But the rest really sounds like a kit, and I'm not really fond of that in these types of songs. Seems a little to classical for a regular old drum kit.
You might think about a french horn line somewhere. If there is one thing I've learned about composing, it's that you can never go wrong with a french horn in the mix. By far the most beautiful sounding instrument in the world. I think it would add some nice color to this song.
4/5 and 8/10 overall. I really like it a lot, but I do think it has a kink or two to work out.
Great job here bud!
