The horn piece was really pretty. I believe there could be just a little bit more, though. Granted, that's probably my personal taste speaking, but...yea, just giving you what I think.
As for the flute piece...how do I say this lightly... I love it! I mean, it's simple, yes, easy, yes, different, most definitely. I don't know, maybe I don't know enough or something, but I loved it. There were a couple of notes that I didn't agree with, but other than that, it's a great idea, and it somewhat reminds me of 'Somewhere over the Rainbow'...
Great job!
