I have a close relationship with this piece - arranged it, recorded it, re-arranged it, and on and on. I'm curious as to why you only used the strings, and not the full orchestra? This piece - simple as it may seem - is a real lesson in orchestration. This presentation felt like I was hearing only one channel, with parts missing. I'm sure that wasn't your intention. But it did highlight the inventive string scoring Falla uses, as it would be simpler to just "fill in" the other parts in the same group.
Sorry to be so critical - perhaps I'm the one that's missing something?
