Hey David - I listened a couple of times yesterday and again this morning. It sounds great.
You use so many instruments and sounds that I never use that it's difficult to judge sometimes, but I don't hear any problems with this mix myself. I like that it's sounding more organic than some past arrangements I remember. The violins sound great.
Each time I listened though, I guess I felt like the chimes or whatever those are that come in around 2:21 were a little loud, other than that, nothing stood out to me as a problem - good job.
